I bought my 9 and 11 yr old boys each a black rhino longbow for christmas, my youngest boy will be shooting a M-54 and should be around 12-14# and his draw and my oldest will be shooting the M-58 and his draw should be 22-25# I was wondering what arrows would be the best. I was going to buy some 1/4" poplar dowls, but they just look to easy to break. Should I jump them to 5/16 even if they are way to stiff or should I find them some aluminums or carbons? If so what size? I just hate spinding 20-27 bucks for a 1/2 doz youth carbons if they are going to loss them. I was looking at the easton jazz arrows, they look like they would work.
