Well, I picked up the Palmer from the P.O. this morning, and shot it a bit. I know my arrows aren't spined for it (50-55# 28.5" BOP) and the bow is 58#@28", with me drawing just under 27", but it shoots good. I tried split and 3 under, and the only difference I can see is that I impact 4" low when shooting 3 under, from 10yds. I'll get to shoot it some more after work this week, and I'll post if I have any issues, but it seems that I have little to worry about.
BTW, this thing will SMOKE an arrow, compared to my longbow.
