Man - I am EXACTLY THE SAME!
I don't have much free time these days and haven't done a firmware upgrade in months (not since like 7.04 or earlier). I know that since that time, the compressor, drives, and amps have been vastly changed. I use maybe 90 or more patches live at various times, as I have a cover band that knows a million songs in all different styles. In the year + that I've owned my Ultra, I have been slowly honing my patches to all be the exact correct volume levels relative to each other in live situations. I am DYING to hear the new firmware, but I keep "chickening out" as I just know that if I upgrade, I've got weeks and weeks of my free time out the window trying to get my volumes and sounds all fixed again. I have regular gigs and can't find the time to even attempt it. I LOVE how Cliff is always improving this unit, but I'm frustrated that I don't have the time to adjust everything after I upgrade. I've got 2 little kids at home and NEVER have hours and hours to just sit and tweak uninterrupted any more. I've even considered calling out sick from my day job once to try and do it all in 1 day. I'm guessing that doing THAT won't even provide me with enough time.
Having said that, it's a GOOD problem to have.
I'd rather have the options than not.
