I fly mostly 35%'ers. I also compete in Unlimited in the NC region. Granted, the larger the bird, the better it will present. But you have to factor in the cost of putting a 40% together, versus a 35%. You are lookign at about $2-3K in difference. It just depends on which model/manufacture you go with.

For me, since I like practicality, I stick with 35%. 1- I can put it in my Explorer, and not need a trailer. And 2- cost. I save about $2200 +/- between the Carden 35% Extra and say the CA Super Extra 3m. The 35% and smaller are easier to transport, thats why I stick with them. Otherwise, I would be flying 40's all day long!!

HTH....
