I agree, fast moving or deep areas are best for the sink tip. I have also found its great with a big swell coming right at you too. My floating line or clear intermediate will pile up at my feet with those conditions. So, I throw the sink tip on the back side of a wave, and start stripping. (You definitely don't want to wrap line around rocks, losing a fly is bad enough).

I have to admit that most of the time I use a floating line with a sinking fly around the rocks. It gives me access to many areas where I wouldn't throw a plug or lure.
