hey i used to work out at rancho san marcos. it was one of my favorite courses before they re-did a couple holes and i joined la cumbre country club. i actually caddied one day for jimmy connors when he played a match against michael jordan out there. but i digress.
as for fast greens, it's just a matter of your comfort level. if you played at RSM more regularly, the speed of the greens wouldn't be an issue and you'd actually probably enjoy them more than slow greens.
you'll probably 3 putt less often if you focus more on the speed of the putt(ie: getting the ball close or tapping it as you said above), rather than the line. remember that if you get the speed down, but your line is off by a couple inches, well that just means your tap in putt is going to be a couple of inches rather than a couple of feet if your speed is bad.
hope that makes sense.
