Aeromasters and Ultimates will work great for what you want to get out of your flying Dean. You should have lots of fun with either or both. Let me suggest that you build them as light as possible. The Aeromaster as originally designed by Andrews was built like a brick outhouse up front around the engine. Thick slabs of wood abounded. Yet, it was extremely weak just aft of the lower wing. I saw a few of them over the years break their fuses in half just aft of the lower wing. He used 3/32" sheet there and no additional reinforcement. You may want to reduce the beef up front a little but definitely add some 1/64" birch ply on the fuse sides just behind the lower wing's saddle. You don't want to add too much weight there of course, just enough to strengthen this weak area. You may compensate for the CG shift aft by building the tail feathers a little lighter. Good luck
