I don't have personal experience shooting them, but did run into a bowhunter from Australia up in the NWT last season. He shot the OZ Cut Elite one piece heads and was very happy with them. He hunted pigs in Australia a lot and they did a good job for him on pigs. He shot a nice Dall sheep "end to end" on a frontal on that hunt as well. He said they sharpened up well, were easily touched up and are tough as heck.
I looked at the heads and they look simple and tough. I'm not a two blade fan, but if I was I'd consider them. Good luck!
