Well, I have had excellent results with 4 blade 100 grain slick tricks. They are an excellent broadhead. I believe 5shot has a review of these as well you could check out.

They have impressed me more than any other head I have shot. I would put the muzzy 3 and 4 blades a close second behind the slicktricks in my experiences.

I perfer a 4 blade broadhead, they seem to really open up the wound channel.
