I sometimes do it in Masters races if it's my second race of the day. Like UMD said, it's pretty smooth and fast. You can let a little gap go before the corner and then just roll through with speed and come out right on a wheel. You need to be very attentive to gaps and jump them right away. I tail gunned a 70 person masters race earlier this year, 27 mph avg. speed on a 6 corner crit. Ended up 24th, was happy with that as it was the 2nd race of the day for me.
