I always just left trigger spammed to either center the camera or lock onto the monster. The claw always seemed a great way to give yourself some kind of RSI.
I love the way logi mice feel, but I've had 3 die on me with a double click issue, I just can't bring myself to give them more money.
I've heard that the Xenics Titan is built well, but has abnormally high click latency, which I'm not a fan of. Right now I'm sticking with an old school Razer Deathadder wireless, but you're not wrong about their software being a cancer.
