I typically steer clear of the What ____ do you use type threads. Fair warning, I do pro staff for Rage. That said, I can't imagine liking a head more or having better results than with the Rage Xtremes. As MO wrote, it isn't for when you hit them good. The reason I love the 2.3" cut diameter (actually turns out to be a bigger hole than that, due to dimpling) is the result of the times I don't hit them well. It's only been 2 years now, but the 4 deer I've gut shot and one pure liver hit I made all died within 100 yards, I heard 3 of the 4 gut shot deer topple (didn't hear the other, but it "appeared" to have dropped, instead of laid down) and the liver hit died the same as a double lunger would have (while running). That's why I flat out love those heads. They forgive a lot of sins...And, as with any head, they do the job when you hit them well, but it's the bad hits I worry about.
The one potential downside of the Xtremes would be lower poundage bows not getting good penetration when hitting the shoulder. Personally, I don't worry about those. If/when I do eventually hit a shoulder with one, if I don't get good enough penetration to find that deer, odds are they'll live a long and happy life afterwards. I'm fine with that. The deer that have tore me up over the years are the few I've gut shot and didn't find, as I could never shake the thought of it laying out there somewhere dead and going to waste because of me.
Reagan, I agree on the old style Rages. Since the same company also used to produce Titanium 100s (they bought Rocky Mnt Broadheads), which was a fixed blade, I pretty much shot them until they came out with Titanium Rages, which were better at holding the blades than the original Rages. During the brief time I used the originals, I actually had one blade open in flight, resulting in me severing the Achilles tendon on the back leg of a really good buck. Luckily, I was able to get a 2nd arrow in him to finish the job, but, between the blades opening in my quiver, O rings snapping and the risk of deploying in flight, I refused to use them after that brief experiment. For the last 2 years, they've had a completely redesigned system for holding blades in place on all their heads. Now, it isn't even a minor concern.
