A lot of aerobatic planes have this "problem" on landing approach, you come off the power, the plane slows down as expected but ballons at the same time. Worse at higher speeds and if too fast the plane is pitchy as hell even on low rates.
While I have seen people make things easier with spoilers, thrust and CG changes, making the leading edge thinner etc., these modifications aren't always condusive to 3D type flying, and I prefer to fly the thing in. I think the main thing is to realize that these types of planes will not land like a typical trainer, you will have to fly it in with throttle and all your controls. You have to sort of harrier it in as others have mentioned. Also you'll probably have to find a slower approach speed to lessen this charateristic. You already have part of the solution...
...and then at the slightest throttle its staightens out forward....
you just have to find the right altitude and speed to straighten out the plane onto the runway. Just a blip onto the runway. Once you get the hang of this I think you'll enjoy this plane at even twice the wind speeds you mentioned and perhaps be able to even fly backwards.
The smaller Twist probably does not exhibit this due to its higher wing loading, but is less of a 3d plane as a result.
Good luck!
