RE: Stirring the pot.....again. Penetration
David, I shot 2219s at 70 lbs. using fingers years ago. Went down to 65 lbs. using the 2216s(one of my favorite all time shafts), then played around with 2213s. Currently shooting Easton Carbon Evolution 400s, which are very comparable in weight to the 2213s but with more spine of course.
Badshotbob, although I get passthroughs more often than not, I honestly believe I do not get the same punch with the lighter arrows. 60 grains or so will not make me lose much speed, but gives me added punch on a less than perfect shot, one that may encounter bone. Plus, Limbsavers notwithstanding, shooting heavier arrows makes my bow setup quieter.
I really like the looks of the Easton A/C kinetics......heavier than most if not all carbons, and containing an aluminum core.
