Thanks guys for the responses. The more I think about it I am leaning toward the ST 3000 that I have. It is one of the later models "K" series that has a ST4500 carb with a bushing in the barrel to restrict the flow. If i use this or a moki I should be able to keep the weight down to around 10 1/2 to 12 lb range. The ST was on a 80" sport plane (a Q-500 blowed up and modified to be more aerobatic ) it weighed 10 1/2 lbs. The performance was awsome. The One Design I am planning to sport fly and try to learn some 3-D. Yes I have been bitten by the 3-D bug too!!!!!
I like the looks of the One Design and there is not a dozen of them at the field when you go flying. I like the other planes but I just want something a little different.
