The NAP Nitrons, Rocket Ultimate Steels and Slick Trick 100s are my current non-expandable picks. All fly very accurately and are extremely durable.

For an answer to your question.

I just started using the WacEm broadheadsthis year. Thouroughly impressed. Fly exactly like field points. Phenominal penetration.
Poked a hole in a nice 5X6 whitetail this Sept and he didn't even flinch when the arrow passed through.
Using Blazer 2" vanes with these broadheads. Great performance and durability. Tough set up.

Highly recommended.
