I'm still running 3300's at times as i only have a few 3800's which are awesome.
The main thing you notice with 3300's now is the severe lack of punch compared to 3800's - When you race on a track with some high grip or big jumps you need to clear, 3300's are a big pain in the back side so i don't think many people would like them now they're all used to 3800's an upwards.
