I think tubs are easier to use now than they ever have been. I have ridden Tufo S3s for the last 8 months with no punctures. Use their self-repairing puncture liquid and Tufo extreme tub tape and you are away. Tufos have a pretty crap reputation with Time Trialers for their perceived high rolling resistance, but for street and/or amateur road racing they are really easy to use. And even as a street rider you will definitely notice the better ride quality from tubs.
this is my experience exactly
