BIGBULLS That's why all mechanical blades are against the law here in Idaho. I believe you mentioned 4 fixed blades, those are good blades. But don't be to quick to discount muzzy,thunderheads,and like broadheads. Those 2 heads take more elk than anything else in the area we live. We've used both and have drove them clean through both shoulders of elk, not leg bone, but shoulders. If you think about it theirs nothing there to stop a well tuned broadhead with a bow set to 60# plus. I've used the fixed blades before and find them much more difficult to tune, than muzzy or thunderhead. My son and I use muzzy 100 and 125 we shoot minimum 480grn arrows at 74lbs. This works great for us. Hope this helps. elknut1
