Will I be spined properly?
 

Ok I’m thinking about this arrow setup for next season. GT pro hunters 7595, @ 28” with 125 gr head and 50 gr insert.
They will be shot from an 07 Allegiance, 70# @ 29”.

I think I will be fine, just wanted some other opinions.

Your going to a tad weak even cut to 27". But cut to 27", it should work. A 100gr head might be a better choice according to Ontarget. This was putting in a speed allegience. With you have a smooth allegiece, then a 27" with your insert and head will work.

Thanks!
I do have the smooth mods, and could probably get down to a 27” arrow. I just used 28” cause that’s what my old ones are and I know I have a lot of room to spare.

One thing I’ve noticed from shooting trad gear and I don’t know if those programs account for it, is that 200 grains up front between the head & normal insert, shows weaker than 200 grains up front with a 100 head & 100 insert. I am guessing due to the weighted insert shortening the effective shaft length because it is deeper inside the arrow.

You could always drop a pound or two and shoot at 67-68. That solves a slightly weak spine real quick.

Or you could buy an arrow with a stiffer spine.

RE: Will I be spined properly?
 

So you got alot of experience with spines stiffer than 0.3"?

RE: Will I be spined properly?
 

No, I guess I figured that there must be stiffer arrows. I know that the 7595 is as stiff as GT makes them, but If I can buy a bow with 80# and even 90# of draw weight, there must be arrows to buy for them.

Actually GT does make them in thier 7595 trads, and so does Carbon Tech, just figured, since you replied, you actually tried them.

I haven't shot GT in 3 years. I like CX much better.

Yea, I would suggest if you are a tad weak then drop your weight a few pounds until you tune.

I did just run your setup in OT2 and I have it almost dead perfect as far as spine. You should be very close with that set up.
