3 for me because RadSav told me to.  Hasn't been an issue so I'm not going to change anything

I did? I've been having a lot of senior moments lately :chuckle:  Did I send you some MAX Hunter vanes?

You said if 3 with the 6 degree bend made by my Arizona E-Z Fletch mini was working, don't change.

Here's what you sent me (no lable on the package)

Yeah those are the MAX Hunter vanes.  I did not like them as four fletch.  A little too big of profile and a little too heavy I think for 4.  As a three fletch they are wonderful!!!  The extra profile gives as much as most others in 4 fletched so why waste the additional fletch.  Blazers I'll take either way and really like them as four, but 3 fletch only with the MAX Hunter IMO.

I love them.  They fletch easy and damn near indestructible

I use 4 fletch primarily because I don't want to pay attention to fletch orientation in the heat of the moment...just snap it on and shoot.

So I played around a bit today with poundage and spine aswell as fletchings . I found the new cpxl  shot a 250 carbon express at 61 lbs and 29.5 inch draw killer . at 66 lbs the 350 spine arrows only 20 grains heavier fell off quicker . I was shooting really well with the three fletch 250's so I screwed a broad head on one a shuttle t just screwed it on with the factory three fletch and cut the flecthing right off at 40 yards . now in questioning my four fletch set up . maybe because the foc was higher on the 250's ?

i spend many sleepless nights building new arrows.i have yet to find any good reason in my shooting to use four fletch.
i have moved back recently to a 3 inch vanetec with 575 grains of arrow n 18 percent foc.
i have yet to have an arrow fly as well as my high foc set ups.seem more forgiving of everything.with the exception of yardage estimation.due to overall weight being higher therefore slower

At 30" draw length and arrows 29.5" in length you are really pushing the limits of what the 250 can do out of the Insanity CPXL.  Not sure I would be that brave with an all graphite arrow.  Even the 350 @ 66# is pushing it beyond where it is recommended.  With the four fletch and assuming you are using the Blue Streak or Maxima shafts the difference in overall drop at 40 yards between the two different set ups you mention should only be a couple of inches total.  And drop per yard at the target should only differ about 1/10th of an inch.  So if you are seeing the 350's at 66# dropping off much quicker there has to be a problem somewhere as long as you are not using full helical and quickspins together.  FOB is a good bit different and being close to that 12% mark on the 250/61#/3 fletch might be the difference to some small extent.  But it could be that you have the bow tuned just right for the extreme paradox in the 250's that is not there in the 350/66# which are closer to a match for your bow than the 250/61#.
 
Even with 4 fletched Blazers, lightweight Maxima/Blue Streak and a 9.5-10% FOC you should not see any fluflu effect. You are not reaching the apex of the arrows parabolic curve with the four fletch/350/66# until nearly 120 yards.  So there should be no issue with three or four until 20 yards one way or the other from that point.  I myself would shoot both arrows at 40 yards using the exact same pin setting.  If the groups differ more than 2.5" I'd say you are having a tuning or spine related problem not a fletching problem.

Myself, if I were shooting that long of draw length and that long of arrow I would be shooting the 350 at 61# and a 300 spine arrow at 66#.  And I would not be worried about FOC or 3-vs-4 until I knew I had any spine issues and bow tuning absolutely perfect.

Rav I hear you thats why I was gonna stick with the 350's . I shortend the draw length to 29.5 since it felt a bit long and backed it down to 61 to just play with it . it was shooting the 350s well but really fell off at 40 yards ( shooting perfict paper). I had a box of maxima 250's with three fletch blazzers and according to the spine chart i was right at there limit . I can only assume they have a bit of saftey built into there numbers ? . when I went to the 250s with 100 grain tips It dropped my arrow weight approx 20 grains and the groups tightened up I can only assume that it was because of more front of center ? any why my pin gap was tighter than the 66lbs set up with the 350s out to 50 yards atleast . I just figured that I'd try a broad head so I scewed a shuttle t on and it flew right with the field points 20, 30. and 40 yards . Can I assume that I'm not underspined if the two set ups fly that well ? at 61 lbs my 250 set up is at 295 grains give or take a couple well over the leagal limit , and the 350 set up is at 419grains , my thinking is  if the 250's where under spined then the 350s should have shoot tighter groups ? Man I figured after 20 years of this I 'd figured it out . :chuckle:

one other thing I might ad Rav is that the bow was quieter at 61 with the 250's vrs the 350s at 66 ? another pondering for me . the 250's are 30 grains overe the legal limit and the 350's are only 20 grains over at those respected wieghts so I figured that had something to do with it .

Did you mean 395 grains?  I've been running programs over and over trying to make sense of what you are seeing.  What arrow and are you using a wrap?  I'll run a couple more and see if I can make sense of it finally.  But so far you got some freaky stuff going on :o

Sorry Rav yes 395 opps. the other thin I see with the 250's is a slightly higher impact at 20 where the 350s hit closser to the 30 mark at twenty yet both arrows hit the same at 30 . could it be the cam style and axle to axle on the cpxl are just forgiving on spine or maybe these maxima 250's are just rated a little low . they shoot really well and I was expecting to see that broad head go stray but it shoot killer . the crazy thing to me is that the 250s have a better wieght to poundage ratio than the 350's . plus the 250s are accually a lil long so I could take about an inch off them . As quiet as this thing is and as good as they shoot i'm hesitant to not just run with them . maybe this weekend when I'm over east I will play with both of them at 60-80 yards and see how much steam they loose . ? Thanks for all you wisdom I really appricate your thaughts . C
