Sport wing, preferred F1, but would consider a HRII (likely would plan to upgrade to newer engine mount). Pavement and some grass (1800 feet).
Good point on the CG being an even more of a challenge on the HRII, at least with stock gear. 80% flying solo. Some acro, about every month or so just for the fun of it.
I have access to an RV7, which I love, and it's got me wanting more.
