RE: Broadhead recommendation?
I haven't tried the Stingers, but Magnus has a reputation for great broadheads. Grizzlys are tough, but can be tricky to sharpen. Ribteks come in 100, 110, 125, 130, 135, 145, 160, and 190 grains. The newheads they are experimenting with now are 150-315 grains, but not sure yet which ones will be produced. I think Ace also has a 160 grain broadhead--another very good one.
Art, I've never had to modify a taper to get mine to fit. Some folks don't like the ribs (as I understand it, the new ones will have solid ferrules), but they haven't caused me any problems.
Lots of great broadheads on the market these days.
