I too enjoy shooting aluminum. They are a bit different tho. Hitting a target weight is easy as aluminum shafts weight more in thr gpi dept. Efoc is a little different.

I found that aluminum arrows fly their best at 18-20%foc. Which IMO is just fine.

If you are shooting 45# at your draw recurve (which I am curently)

Try one of the following set ups.

2018 with 200 point

2114 with 200 point(my current set up)

2115 with 250 point

I play with arrows a lot. PM me if you have anymore ?’s8)
