That depends on your overall purpose for the boat. Yes i am looking at a Blade. I wanted something I could race 2 up for when/if I find a female or light male crew, yet something I could also race uni then I wanted to and still be competitive. Also had to be 21 century technology. That is why I sold my Hobie 17 and bought the Mystere 4.3 to learn spin on. I think the Blade accomplishes this for me. I know nothing of the M-20, BUT can a boat that big be sailed uni and righted 1-up?
