Watch out putting that broadhead on or taking it off of your arrow. I cut the $hit out of my index finger removing one yesterday and it's still bleeding (I almost needed stitches). I switched to them last year and I'll never use anything else. I put a arrow through the spine of a doe last year and the slick trick actually cut the spine in half. Sufficed to say, she didn't go very far (dropped her like a sack of taters). Good luck and I'm sure you'll be buying a pack or two after you use them. One bit of advice, look on ebay before buying them from the big box stores (Cabela's, Basspro, ect). I found them for $35 for 2 packs last year with free shipping, quite a steal!
