help building arrows!

I've always shot heavier bows; in the last few years I've gone down to a 56# pika. June 21st i had rotator cuff surgery. I'm going to get a 40# bow and don't know where to start. I think I want to go with aluminum. this is going to be used for hunting so foc energy is preferred. I have a 28" draw.

Put this on Pow Wow, and you will get more responses.

Start with the 3Rivers shaft selection chart for your bow and work up from there.

2016, 2018, 2117 depending on tip weight, form, bow set up

I am not sure but, maybe even 1916. 
I will say I used Three Rivers spine calculator on my last bow and it came out spot on for my 51# BW  and 2117.
My 47# Tall Tines likes 2016. Depending on tip weight.

What I do like about aluminum and wood for that matter, I don’t have to think much about total arrow weight. On my 2117s with 51# recurve it works out to 10-11 gpp.

Nothing heavier than a 1916 (53# spine) unless you have a very high performance bow and or front load the arrow a lot.

If you like higher FOC, I do, then consider carbon.  I run 500's full length (30 1/2") with 100 gr inserts and 150 gr magnus heads.  Perfect flight!  Right at 500 grs. with my 40# bows.  I have a 28 1/2" draw

I would consider carbon shaft, easier to get a high FOC and a more efficient arrow for hunting. If you want a shorter arrow than what Stan V is suggesting, you might want to try a 600 spine.
