I recently took a 1500-pound Water Buffalo in Argentina with 125-grain Thunderheads. Broke 2 ribs that are like 2X4's and didn't lose a single blade. The broadheads stayed perfectly in tact and with some replacement blades, they were good as new. I was impressed with their durability, not to mention their effectiveness.

I'm sure Muzzy's are the same and they do cost a bit less.

Actually, for game as small as whitetail deer, there are MANY broadheads on the market that are equally effective. I like Spitfire Expandables also. They shoot great and make a helluva hole and are great for deer-sized animals. When going after bigger game like Elk, Moose, Water Buffalo, or some of the big Africa Game, broadhead choice becomes a bit more critical.

Get a good quality broadhead: Thunderhead, Spitfire, Muzzy, Satellite, and you will be fine for deer.
