RE: Questions about Arrows, Speed, etc. etc.
If your bow has 60-70# limbs, and you are shooting a few times a week, increase the poundage by 1/4 to 1/2 turn every week or two. Many will go over 70#'s by a few. You will not really notice the increase in draw weight and you will gain speed, without changing much else. Since you are just playing, it might be fun to see what you can get.
