I've used alot of different heads. Expandables I threw out the window last year. I had to many things go wrong with to many differnt kinds.

I wentback to a fixed blades this year. Stinger SS. It's the sharpest I've seen out of the box. Most test tell you heads like this get the best in penetration and are very durable. One more great atribute to this head is that it groups right with my field tips all the way to 50 yards.
