Since i had to drop to youth shooting weights a few years back, I have tried a lot of arrows. My draw ability fluctuates with my health so I keep several different spines of arrows on hand. Best solution I have found is Easton Jazz... not carbon, but they work and have done well. They come all the way down to 1213. I have a dozen shafts on hand in that but haven't had to go there. Mostly, I use 1416 or 1516, full length. If you shop real hard you can find tips with attachable inside weight systems even that small. I have shot as low as 16# in 3D. This year I'm lucky, I'm up to 22 - 25# 8^) Oh, yes... my draw varies from 24" to 26" depending again on how I'm doing.
