RE: Sidewinder 4
Actually that head is not a solid head but has the pathfinder point. The thing I don't like about that head is the thickness of the blades which may seem counter intuitive but when you go to that much cutting diameter I would prefer a blace that would be thinner and would tend to bend when encountering heavy bone. And in that regard I would prefer the miniblaster 3L with the pathfinder point. A little more expensive but a configuration that I think would perform better on the not so perfect hits.
That is a great price though.
