RE: question for Ian" iSonic or S-type
well, following the above, I got myself a 125 iS last weekend.
Sailed it monday in a good 4-5 with a 7.9 diablo. This was slightly overpowered in the gusts, but unbelievable how fast the iS already felt (and according to the guys on the beach actually was!!). The feeling was very similar to the ST, ie sort of a hovercraft/floating over the water type of ride, only the iS stays much flatter than the ST. This provided for a very safe and fast feeling. It was a bit more difficult to get planing than the powerglide, I think mostly because it is so much shorter and the pumping technique probably should be a bit different.
There is still a lot of tuning and adapting of my technique to be done (I now had some spin-outs (small fin) and almost no pressure on my front foot).
Anyway, yet another great *B and I can't wait to get out again!
