Though not on boar, but on bears, deer and small game I've used Quad Pro, Montec and Bloodrunners. So far Quad pro has given me more game but thats because I used it the most. Just this season I switched to Bloodrunners 2 blades. I got 2 deer and 1 bear. They make a nasty cut your fist can fit into.
Basically, whatever BH your tuned to so you can make the best shot.
