330 tire here as we'll, split log and I ride together quite often and we both have a 330 tire, we ride with others sometimes with smaller tires and never have a problem hanging with the rest of them. I'd say just get comfortable with your bike and it will come natural. I was nervous at first going from a 250 to a 330 but after I got a feel for the bike I feel just as comfortable on mine now. Only time I have to slow way down is real short tight corners because it sits so low and no suspension.
Just thought I'd share.
