I just swapped from a Diesel 65 to a small Burn and I'm very happy with the swap. I paddled the Diesel for several years in all sorts of water - big, small, hard, not-to-easy (... easy is play boat territory ..). I have the new (2010 model) Burn, and I think it's faster, boofs better, and it sheds water a lot better (more peaked deck) than the Diesel. And it surfs better and pearls less. I think Pyrahna underestimates volume, or Wave Sport overestimates as the boats look to be virtually identical in volume (the S Burn is supposed to be 63 gals but who knows). I don't feel much difference in stability or ease of rolling (both roll easily). If you set the boats side-by-side and compare the hulls, you can see why the burn accelerates so much faster - the shape of the flat part of the hull is quite different in shape. Can't speak to the Villain, but I'm very happy with the Burn (and I really liked the Diesel). One down side is that I find the Burn really uncomfortable to carry, and it takes a skirt with an XL deck (i.e., your Diesel skirt won't fit a Burn).
