I've seen the TTSX and E-Tip used considerably, and also seen the GMX used to a lesser extent on game from pronghorn and elk-sized nilgai, including a big bull taken with a 150-grain from a .300 Winchester Magnum. While there are slight differences in discernible performance when shot into "media," I've never been able to tell the difference in the three on game. I'd also be perfectly happy to use 150's of any of the three in a .300 magnum on elk.
Have also used the Cutting Edge Raptor some, enough to know it would work as well. It's designed to lose the petals, however, so wouldn't please some hunters.
