Could you arrow experts help me ,help a guy at work who jumped into the traditional archery area with both feet. He bought a Stalker recurve with 2 sets of limbs. 1 set is 47#'s @ 28 and the other set is 50 's @ 27 inches. He draws a solid 27 inches. The bow is cut 3/16's past center and has FF string on it. He is dead set on shooting aluminum with 150-to 160 grain points, and he shoot spit finger. He has collected some 1916s,2018's ,2016s,2314s. what say you on these arrows ,that would be the best to accomplish what he is looking forces in what length for which arrow. I shoot carbons and have some GT 500s,and 400s that Id be willing to cut to see if we can get him pointed in the right direction. He will be shooting off the shelf. ant help would be most appreciated. --thank you for any info
