Yeah, I'm curious about the S33s as well.
I have a Tufo S3 Lite 21mm (tubular-clincher) on one of my front wheels. Out of the package, it's very sticky...which may be good or bad. Good that it's sticky to the touch. Bad in that it may simply grab a layer of dust and hold on to it.
I've only used it outdoors on concrete. I'm curious to know if it would be appropriate for use at ADT/LA/Home Depot/whatever it's called.
