I've killed two bears, one with a Phantom 125, and one with a 4 blade Muzzy with my compound. Both performed awesome. Also shot Muzzy 3 blade 125, Wasp Jak Hammer 125 and Rocky 125 Ironheads for deer. All performed well. Blades were sharp on them all and the heads were well built. Had real quality problems with Satellite heads, blades broke, bent ferrules, real poor quality. Could never get Snuffers sharp.Now that I took up traditional, think I'll switch to Magnus 125. Was looking at the G5, kind of expensive, also the Steelforce. Looks like I'll probably end up with another collection of bradheads. On the Technical archery forum, 5Shot does some great real world broadhead reviews, check them out.
