I’m in almost the same situation. Have an older Formula (260x94) that I use with 9,5 race sail in light wind. Then wind picks up I change down to 7,1 freeride 2-cam that I also use as largest sail on my Carve 121. (and then to 6,0 camberless ,maybe buy some smaller also)
I now thinking of get something between these (hopefully often to use instead of the Formula). I maybe can get last years iSonic 133 (or 145 or 155 or a used Apollo-07).
There are also Carve 161 dram but that maybe will be too much “detuned” and I can’t afford a new big Futura that maybe have been the best choice for me ?
Any advises (weight 78 kg) ?
