Dan, that's a pretty fast transition time. I think a big time saver is to try not to use a full wet suit, if possible. I was really surprised, because the lake we swam in is at about 1500 feet above sea level in the foothills of some mountains. I thought the water temp would be very chilly this time of the year, but it was 65-66 degree. Maybe a shortie is more appropriate. I like the buoyancy a suit give me, so maybe a shortie? Or are they overrated? Thanks!
