Nice airplane
I own and fly a 7a and a Champ 7CCM and I love both of them. I had the opportunity to fly in Bill Hollifields RV12 a little while back and think it might be a lot more "airplane" than the Champ. Compared to the Champ, it's a lot more maneuverable, quicker, more responsive, cheap to fly, an all round great airplane. It's not a 4,6,7,8,9, or 14 but those are different missions.
If there is any dissatisfaction, I would suppose it would be the "I wish I had done this" or "I wish I had added that" but certainly not the "I don't like the airplane" kind.
Just my .02
