RE: steelforce broadheads
I have read 5 shots reviews of Steelforce heads and agree. They are decent broadheads, but nothing special. Only thing I don't like about them is the unsupported length of the blade from the end of the ferrule to the tip. The tips tend to bend and/or curl when they hit bone and, naturally, that kills penetration. Keep 'em away from bone and they do just fine.
Of course, we all know that in the woods everything always goes exactly as planned. Right? [8D]
I'd be more inclined to go with Magnus Stingers, myself.
