We have similar benches at one field and i agree, they are not that great. Put a true low wing taildragger with a lot of power and the plane will tip over forwards at full throttle. Scared the crap out of me the first time it did that. I now only work from the ground.
The solution to that problem is to pull up elevator while you go full throttle. You'll have that problem with any sort of wing hold-back, on the bench or on the ground. I don't like tail holdbacks, since the tail of the plane is not usually as strong as the wing. Even on the ground, I use long stakes for wing holdbacks.
Yes that will work but it is very hard to tune the engine and hold up elev at the same time.
