I've been using the Magnus Stinger 125gr 4 blade since about the time they first came out. I've killed a bunch of critters with them with zero failures and zero problems. Lets just say it would take alot to make me change from them. I've used the exact same broadhead to kill numerous critters with just some touching up between. They sharpen easily, stay sharp, don't rust, fly quiet, penetrate, durable, cut going and coming and you don't break the bank buying them. I make my own bows and the last one I made I just named it the "Stinger Flinger"
