RE: Wild Hare Ultimate CG
The only bad habits the Ultimate will have would be induced by using excessive control travel. The plane is extremely responsive, and quick. If you use what's been pretty much the standard 3D travels used on most mono planes it will be too much. More than 30 degrees or so of rudder is excessive, as is any aileron travels over 28 degrees. 40 degrees of elevator wil take you anywhere you may want to go.
Plan your landing approaches as you would just about any bipe by allowing for a little steeper angle of descent the first time or two. Most bipes don't "float" down a runway like a mono plane, but after your first couple of landings you'll find that this Ultimate will land slower than you might have thought. Just don't try to slow it down to a crawl 5 feet up over the runway.
Good luck and enjoy,
