Read the Review Transcript: Hi it's Fidel. I just got done testing Elan's 2013 Amphibio 78. Overall 4 out of 5 stars. Very responsive very quick. The only reason I dropped it down to 4 is that at higher speeds it kind of chattered a little bit for me, but I am a bigger guy. I think if I probably was 20-30 pounds lighter it would be an awesome which would have no problem holding it's edge. Really enjoyed 4 out of 5 stars.
