i have been shoooting a youth bow, i got when i was 13, for the past 20 yrs. this year i decided to pass it down to my son and upgrage. i just bought a pse brute x. great bow but alot different from what im used to. faster, lighter, preloaded limbs, cam, etc. now i need to figure out what size arrow to shoot. i have a 27" draw length, 58lb draw, single cam, whisker biscuit rest and shoot with d-loop and release. any suggestions on arrows type, size, or how to determine? i heard arrow size is critical so want to do it right.
