I shot Thunderheads for years, they were are fantastic.
Plain, Jane 85grners work great for lower poundage bows. Not nesassarily good blood trails, but all animals died in sight, with complete pass throughs and draw weight 50< lbs.
There aren't any
bad broad heads out on the market nowadays. Even the Rages work pretty good for certain people, myself included. I've been recommended Killzones, GrimReapers, SlickTricks, Rage 3s, and Ramcats. All seem to get the job done. My suggestion would be to look at what you like, try it out a few times, and if it works, then stick to it. If not, there are plenty of more razor sharp fish in the sea
. Like with bows, it's YOUR preference
