Closetguy makes an excellent point that has been overlooked before his post; the Evolution is about a pound heavier than the DLE since it's actually a 60 size engine.

All I have is anecdotal evidence base on what I've seen of the Evolution egines around here vs. what I see posted on the forums and that would suggest that while the Evolution is supposed to be basically the same engine as the MVVS, the MVVS doesn't seem to have the reported problems one sees with the Evolutions. Based on what I've seen around here, there's no way I'd be buying an Evolution.

JMHO, YMMV.....
