RE: time to pick a broadhead
The sharpest broadhead that I've bought so far is the G5 Striker. It flies really well (same point of impact of field points) and super accurate. After shooting it into a block target twice it is still sticky sharp! Haven't wacked a deer with it yet but have no doubts as to how affective it is.
I use Magnus Stingers on my crossbow because of its reputation for toughness. No kills with it either.
This is the first year for not using Wasps which have been 100% affective.
