iSonic 90 or iSonic 87

[emir633]

Hi Kevin,

I've got iS101 and Loft Blade 6.2 and I want to add a smaller board and a bigger sail to my materials. I bought Blade 7.0 (gonna use it with 101). I am 77 kg and 187 cm and I'm still growing So which board would be better for my 6.2 sail? iS 90 or iS 87?. I think I will use it +20 knt.

Thanks,
Emir
