solsoler................I weigh 150....have the contra 14.....and can ride my custom 133 as soon as the kite can fly..........make your judgements from that
I am sure the 14 and 138 would work for your weight....
get the 14 contra try with your custom 133 ....if it doesn't work get a slightly bigger board
I thought I needed a bigger board for light wind 8-12knots....then found out my custom did the job no problem.......I had a 149 ss glide that I couldn't hold at 8- 10 knots
