Thanks for the reply Bill. Turns out that after some measuring in my car I need to go smaller or I have to have a removable stab. Sooo... currently I'm looking at the CG Yak 54, CG Extra and H9 Extra 260. Either the OS 1.60 or maybe a Moki. (who sells those anyway?) All are about the same weight and wingloading. I think any of those would be a good IMAC/3D combo.
