Everyone seems to rage about the Slick Trick and they may be a great broadhead but I've never tried them my self. Two years ago I switched to Magnus Stingers (100 gr - 4 blade). They hit exactly the same POI as my field tips. In these two years using them I've taken 2 buck, a bison, and a bobcat. Both deer ran only a short distance and then began walking away and expired within 75 yds of where they were shot. They acted as though they got stung by a bee or something. The only 'drawback' with the Stingers is that the aluminum ferrule has a tendancy to crack when it hits something really hard. But you send it back to Magnus and they send you a new one.
Another broadhead that I hear good reports on is the G5.
