I just want a good 70 hp that is smooth and reliable. From what I hear the VA 70 is pretty close to stock feel but I hear the Edge EZ is also smooth. They both sound comparable so I'm wondering which is more reliable? I don't want to mess w/the tranny, I just want a mellow clean boost. I've searched and I know it's been talked about a bit but I'm down to flipping coins on this one. Also does anyone see a problem with a used unit?
