Hard to say without laying my hands on it, but it sounds like fletch contact or cam timing.  Try tuning a bare shaft, maybe.  Or spray foot powder on the arrow to see where it's hitting the rest.  Next, I'd look close at cam timing (yes, it matters on a single cam bow!).  Here's the Mathews' link to see how to check it: http://forums.mathewsinc.com/archery-4/technical-faq-28/cam-timing-2009-mathews-bows-103809/?sid=04d873da09c959d8976952e62a8dbe1e .  Remember to check cam timing only at max poundage of the bow: a 70# bow set at 65# will not look to be timed correctly until you crank it up to 70#. 

Otherwise, I'd start back from the beginning: rest height set so arrow goes through center of Berger Button Hole, nock height set exactly perpindicular, rest elevation set at Mathews' standard 11/16" from sight window to center of arrow.

It sounds like you may have been trying to tune the bow and went past the perfect spot of the rest height or windage to where you induced fletch contact and just need to restart from the beginning, but that is only a drive-by guess.

Good Luck!

The goldtip chart says you should be shooting the 5575 shaft.  I know you said you tried a weaker spined arrow, was it that one?

[carpsniperg2]

yeah that is really stiff for your 63lbs as long as your broadheads shoot strait i don't worry about it to much.

[huntnfmly]

yes it was a 5575 that we tried and we got the same bad tear.when we have the arrow level and square to the string we get a tear that is like \ that and is about 3-4 inches long and the timing is dead on and even when we cranked it all the way up that woukd take care of the spine it is the exact same tear.The arrows have feather vanes so i dont think the contact if any would do that but i dont know thanks for all the suggestions its kind of driving me crazy right now

[carpsniperg2]

ok explain,

The arrows have feather vanes

so are they feather or vanes. if they are feather, some rest will kick the arrow all over the place if you try to shoot feathers threw them. if that is the case i bet that is your prob right there.

[huntnfmly]

sorry about that yes the fletching are feathers and it is a hostage pro It is very discouraging.

[carpsniperg2]

we will get you lined in. if you want to stick with that rest i would change the feathers. if you want to stick with feathers i would switch the rest all the hair/fiber rests that i have been around from the whisker bis to the hostage are very hard to shoot arrows threw. a guy showed up at the shoot with a new rest on his bow a whisker and he was shooting feathers funny as hell 6 shots in about a 20 foot area  i bet the feather are getting messed with my the rest

[hunt4]

Sorry i do not get it how the heck does it matter if his fletching is vanes or feathers?  There should not be any fletching contact with a hostage the arrow sits on the brushes

[Todd_ID]

That rest is basically a no contact rest as far as the vanes are concerned, so feathers vs. vanes is a moot point once you have it adjusted right.  Try the foot powder spray on them to see if it's hitting somewhere.  I'd bet you accidentally adjusted it too far and induced contact somewhere.

[carpsniperg2]

yes but one thing he did not say was how many feather he is shooting? you guys are assuming that he is shooting 3 in that case no they would not touch "if tuned right" but as a trad archer part of the time i shoot 6 fletch arrows and a lot of trad shooters shoot 4 feathers so that is what i am thinking of because it was not said how many vanes or feather. so there is my point boys there are things still to find out and facts that we do not know trying to narrow it down, and help him out. i am about as big as archery freak as anyone out there and have been around these rests and kinda know what i am talking about.

Same bow, same rest- same problem. The Hostage Pro sets very far back on the bow and that seems to be the problem according to the shop tech (whom I respect) who retuned my bow. Though my bow is now tuned and my broadheads shoot true I am going to try another rest. Sure liked the Hostage Pro.

[carpsniperg2]

another thing i thought about lats night was most modern archeres are shooting 2" style vanses. yes some still shoot the 4" etc but what i am thinking because i have fletched tons of arrows. is that is you are shooting a longer feather like a 5" shield cut and the jig that fletched them id cranked all the way over with a lot of offset that feather will really wrap around the shaft. most people are use to noraml platic vanes that are fairly strait on the shaft but if your feathers have a lot of offset to them then when you shoot this could account for the feathers turning enough to touch your rest when you shoot. the other way to test to see if its your arrows and not your rest is to shoot someone elses arrow that is spined right for your bow. if it shoots them right and is punching bullets then you know it is your arrows and not  the rest. but if it shoots them like crap 2 then your rest needs to be played with and maybe your knocking point

This is great info. I had a problem getting my QAD to paper tune properly,I was just out to far.  Start out at the 11/16" you will be very close and I bet it solves the problem.

I also bought the Z7 and after fighting my whisker biscuit for 2 years on my Drenalin, I decided to put the Trophy taker full containment drop away on this bow. It is awesome.  I put it on & centered and paper tuned in 4 shots. It is shooting great with both field points & broadheads out to 60 yards & have the same point of impact. I would highly recommend this rest & I will not go back to any shoot through rest ever again. My point is don't fight it for 2 years like I did, if it is fighting you try something else.  I'm loving this bow, and trophy taker drop away.   Mike


Before I get attacked about the whisker I will be the first to admit that it was probably my form causing my troubles. The bow was to finicky for me. I could simply touch my fingers to the grip and change my point of impact by 4". Mike
