I have used several Rocket Broadhead designs over the years....Naildriver, Hammerhead, Sidewinder, Steelhead....and always find myself coming back to the Steelheads. Their short ferrule, modest cutting diameter and angled blade design work very well for me in terms of both accuracy and penetration.

Complaints over the years of either not having the blades sharp enough or there not being enough threads for the head to secure completely into some shafts are definitely well founded....though I have never had a problem with either. Hopefully the design continues to improve.
