Field points. My broadheads of choice this year were/are the NAP Crossfire's in 100gr. I know these shoot a little to the left and even have my rest marked for broad head and fieldpoint. Suptle adjustments are always a foregone conclusion.
However, I am considering going to a two blade like the Magnus Stinger because I read how well they track close to the field point. I have used mechanicals in the past and they too fly very close to the fieldpoints, but wounding and never recovering two Elk left a bad taste in my mouth concerning mechanicals.
