Some Advice Would Be Appreciated............

I just ordered a Wild Hare 28% Extra and I have a Fuji 64 EI engine that I was planning to use on the plane. I have been told by a few people that the Fuji 64 EI would be a bad choice for this plane because of the extra weight and reliability compared to a DA 50. Has anyone here had any experience with the Fuji 64 EI? I would like to hear the good, bad, and ugly.
