RE: Broadheads...
Muzzys and Magnus Stingers are both great choices. I took my first deer with a PSE Nova set at 55 lbs and Carbon Express arrows tipped with a 100 gr. four blade Muzzy.
If I don't shoot Magnus broadheads again this year, I'll shoot the new Muzzy MX 4. It'ssupposed to be similar to the Slick Trick. I was going to shoot Slick Tricks, but I called the guy about an order placed by my friend's archery shop and he said he was backorder by 2 weeks.
About the Stingers, I was taking a couple of practice shots inside this big warehouse, last year, and on one of the shots I flinched. The arrow skipped across the concrete floor, went through the industrial strength metal siding and embedded in thick metal gutters. Not bad, huh?
