How to tell if my arrow is too stiff of too weak?

Hey whacker1 I have the gamer 350 and lamrith I am measuring from the tip of the knock when I measure.

I would bet your spine is too weak, which is why you have the frowny face.

When or if you invest the money in the .300 spine you will have a heavier arrow as you will be picking up about 18-19 grains in the arrow shaft, which will also skew your FOC a little bit.  I would be looking for a 125 grain head and possibly an insert. 

Sorry for the bad news, but I think you got the answers you were looking for or at least pointed in the right direction.

Thanks for the advice I will definitely be getting some new arrows soon. Sucks tho I have 2 1/2 doz arrows and 6 broadheads that won't get used anymore I wish Steve at Steve's archery in walla walla would have sold me the right stuff. I told him I wanted an arrow that was the right length, spine. Which broadheads for a good foc ect. Oh well I'm just gonna start asking questions on this site first before i go to the pro shop. Everyone here is a lot more knowledgable and willing to share and help out. This site is awesome!!!

at that length 2 1/2 doz will be able to be sold as they can be cut down for those of us that have shorter draw lengths.  I can make some handy work out of those in a hurry.  Let me know if you get ready to sell them. 

I would focus on RadSav's tuning suggestions, you might find other issues other than just spine.  I know that i have foudn other issues with my tuning over the years and will be doing some of his suggestions in the near future to improve the tune.

Like whacker said, you may be able to recoup some of your losses. The long a** draw length of yours means almost anyone else can still cut them down to use them, so you should be able to sell them.

If you want to try 300spine without breaking the bank go to Sportmans warehouse and pickup a pack of Vital Impact 300's, they are a nice Goldtip arrow rebadged for sportsmans...  $38/6 with nocks, and inserts.  Sportmans will cut them to length for you free of charge, least the puyallup store did for me. 

30.625" AMO length and 100Grn heads mine weigh 400Grn with a 11.43%FOC.  I added Nockturnals and upped to a 125G head to maintain 12.45% FOC and was 434grn.  Std Nocks with 125Grn heads are 425Grn with 13.67% FOC.
FOC spreadsheet

If you are not going to use illuminated nocks then keep your broadheads and just use them on the 300's.  100 or 125grn they will both give you good FOC.  And even if they are 100's and you plan to use illuminated you could buy Goldtip insert weights as a backup plan to tinker with FOC without buying lots of broadheads or removing and gluing inserts.  If you lived closer I would let you borrow mine or come buy and try different weights out and shoot a bit.

Maybe take bow in to sportsmans and have them recommend a proper length for you as well?

So I finally got some new arrows I got the same victory rip gamer arrows but in the 300 spine. I have the savora del mastro 100gr. Using the amo method my foc came out to 13.9% with a regular knock. And 12.29% with my nockturnal lighted knock. now time to practice!!
