iSonic 133, 144 or 150 with 10.0 sail?

[SwampSurfer]

Hi guys,

Please help me decide what I want

To plane in light wind of 8-10 knots, I am buying a 10.0 sail (TR-4 or similar). All three of the above boards can carry the 10.0 sail. What is the point of a bigger board since we know when it does blow 15 knots, smaller boards are so much more fun?

Will iS 144 start planing earlier than iS133 considering they have the SAME WIDTH?
