Hi Plow
I'm 85kg and I was on a Underground Flex 42 at first, but then switched back to my Naish Thorn 135, which is a lot skinnier, because I found I didn't need my light wind board (and I can't seem to get my feet secure in the straps on the 142)
By 'heaps' I didn't mean to suggest 'huge' - I'd say about 15ft. I only meant that I could jump anytime I wanted to, and didn't have to rely on waiting for a gust. I probably should have been more careful in my choice of words

But I had no trouble with the light wind - and I can assure you it was light: my CO2 17m would have fallen out of the sky on numerous occassions (I know from bitter experience).
I don't want to start the whole 'bow v C' debate yet another time, but for me, they are brilliant! (BTW I've a 17m CO2 for sale -see gear section)
Cheers
Andrew
