Best combination for iS 86 & iS 101
 

I'm gonna use loft blade 6.2 for iS 86 and loft blade 7.0 for iS 101. I'm 73 kg and 1.85m. Which fin size would be better for me?

The 87 replace the 86 and the 97 replace the 101, so you will have all details in this chart, hope this help

All the best

Thanks Remi but I'm gonna buy 1 fin for each board and I haven't decided what to buy.

Hi Emir633,

I have an IS101/2009 and I use a 34 fin for sails up to 6.7m2, without any problem.

If you want only 1 fin, I would choose the 34 because it's also good for the IS86/6.2 combination.

It depends a bit on the place you will use the boards......

On open water/ slalomcompetition/ serious chop you might be better of with a tectonics falcon f1/ tectonics talon design.

Normal crosswind matchracing, or a bit downwind speed a bit more powerfull design would suit better. Under my iSonic 86 I like to use a rather soft but yet powerfull fin (sonntag SL-S 32cm).
