I hear ya - can't afford to risk mine, too dependent on it for too many things. So no blastin' away at 1.1G + for me. Just use settings on the conservative side and load Titan's 'power37' kernel and you won't have any problems. It's really a very low risk mod - if used conservatively.

I just wanted to smooth out scrolling, transitions, etc. a bit. So I just use 250 + 750 and it made a nice if subtle improvement. No change in heat I can detect.

Same with power settings. Tried 'ideal' for a while but the radios seemed kinda unstable (but that coulda been my imagination too). So I use the more conservative 'lv' and the phone is as stable as Twinkies still in the wrapper.

Of course, with higher risk comes higher reward...so before you bump up to 1G ya gotta ask yourself...do you feel lucky?
