Thanks for the great summary. I am the same age and weight as you and find the 6'6 Dom is perfect for 2' to 4' conditions. I find the 6'4 Dom hard to paddle. How does the 6'2 potatonator compare to the Dom in paddling ease?
One thing I dislike about the Sweet Potato is the wide girth of the nose. It seems to resist forward momentum when paddling. Is the 'nator better in this regard?
