I have 11m 2020 however I kept my 14 Dash. According to me the Dash has better low end, not by a big margin for sure but it's noticeable. My kiting buddy got 14m Torch which is definitely very sweet kite with amazing high end esp when rigged w/ 20 lines...
Sometimes he rides his 14 Torch when I ride my 11 although I am bit heavier. Go figure

matter of skills I suppose.
We both got WTFs and that board is veeery nice.
EJ pro looks very interesting also I must admit
