I'm not sure if this is the right forum for this, but I figure it can't hurt to ask. In any case, I'm wanting to order some 100 grain field points from BassPro, but there are options for 21/64, 22/64, 18/64, 20/64. I went to EastonArchery.com but wasn't able to find the exact specs on my arrows. I shoot 2113's. Thanks for any help.
