IMHO Any midwing Extra would do you fine. I fly a 42% Dalton Extra, I have not flown a Carden Extra so I can't speak first hand on them. However I have let to Carden owners fly my Dalton and both remark on how much better it flew than their Cardens. I think this had to do more with weight and engine selection than the kit. I have also flow the 41% Wild Hare Extra and 35% Aerowroks Extra 260 they both flew awesome. I saw the Aeroworks 42% Extra 260 fly and have talked to a couple they have flown it and also flys very well. So which class are you going to fly in? Is this your first year? IMHO if you are flying in basic or this is you first year fly what you have (You already have a 35% Carden Cap)and try and learn as much as you can. In Southcentral Region there are a hand full of Yaks, 1 or 2 Caps, Edges, Katana, MX2, Velox, Ultimates, Staudachers, and Sukhois, but the most common model aircrafts are the Extras. It all come down to personel preference. Good Luck Andy
