I switched to Stan's a few months ago and i think the system rocks pretty hard. I had two pinchflats on one ride earlier in Sept. I did the same trail last week, rode just as crappily (if not worse because of the low light), and didn't flat despite whanging my rear wheel sloppily into some square edged rocks that would definitely have taken out a normal tube.
I don't get normal puncture flats either.
They were, in fact, a total PITA to set up though, and at first I couldn't get the front to hold air for more than a week. After some practice I have it down though.
You may want to go UST and use stan's goop in the inside. Best of both worlds , easier to set up for newbies, near flat-proofness from the goop.
