nub- that's expensive for those things.
Getnbit- I have shot a few varmits with them cuz they were 6$ for 3. That is by far the WORST flying broadhead that I have ever put on the end of my arrow.
Also it is a big as almost every fixed blade head on the market. I would definately suggest as these guys have going to
www.eastonarchery.com/downloads and getting the tuning guide. If followed properly it should allow you to shoot any broadhead successfully.
Good luck.
