the recommended fin sizes for the iS133 are larger than for the iS144??

Someone's dreaming...

Typically the recommended (sweetspot) fin sizes for iS144 are similar to that of the
iS133 (which shares basically identical outline dimensions).

So correctly that is in the range 40-56cm (sweetspot range).
64 would be a maxed out max size. Not sweet. And not very slalomy.

We'll get that amended ASAP - thanks for the note.

Cheers ~ Ian

Any one know when pics of the iS150 will be on-line? Or are there any other pics of the iS150 on the web. I'm getting the iS144 in Jan (I think this when there available in the UK) but would be good to see the iS150 as well. Any tried the iS144 as yet?
