mattyd,
With the ZDZ-60RV, Supersonic pitts muffler, Pro Zinger 24 x 8 Prop,
and 3 1/2" Tru-Turn Ultimate style spinner, my WH Edge 540T is a joy to play with.

I have not had a chance to fly with one with the DA or 3W engine.
From what I've been told from those that have some stick time on
these is that they could not be happier.

So . . whatever engine you put on will be good.

Get what you like and be happy flying this great plane.
