I have an Orra and it's got a super low profile. Good if you don't have big hands. I don't prefer it though just because it's a little on the heavy side and isn't a solid frame which I prefer. I also have a MGX Revo and I love it. It's not a normal revo though, but I will say I've never heard a bad thing about a Revo.
