Slick Trick 125 (100 last year)
Tough as anything out there, and probably the best flying fixed head on the market (See 5 shot' s tests in the bowhunting section).
In MY tests, these heads out penetrated Muzzy 100 Shockwave 100 and Steelforce 100. And the blades looked much better after the dust settled as well....1 REALLY tough head.
I like a 4 blade head as long as you don' t go TOO big. NOTHING over 1 1/4" in a 4 blade head (Slick Tricks are 1 1/8" )
