Uncle Mike thanks for you feedback on those boards.
BelSkorpio your converter is correct. Yes, this means which ever board i end up with while sailing 5.5 it's primary intended size most of my buddies will be on 4.5 and smaller.
I sail my 115L comfortably down to (my) 5.5. At 6.5 most others 5.5 conditions it's 64cm of width helps a lot to maintain speed in the turns and lulls. It would be nice to jump on a smaller board at overpowered 6.5 and ride it down to (my) 4.7. Imagine the water condition on most's 3's.
Thanks guy's !
