I have an RV-8 and I'm considering doing a contest or two this summer. I have just flown recreational aerobatics up to now so this will be my first experience in contest flying which is certainly different, but I'm looking forward to the challenge. I'll start out in Primary and then move to Sportsman. I think the RV can probably even handle an intermediate sequence in the right hands. If I was reading the forms right the only snap roll in intermediate is on the top of the loop - low energy. My -8 is equipped for sustained inverted flight, but I have the heavy engine and prop so I plan to ballast it for solo acro flight (it's at the forward end of the envelope solo).
Now I just have to get my chute repacked....
