AI2 or TI for solo adventure challenges?

Is that to say that the cables on the SUP implementation are more robust?

I have no idea, likely a slightly different design. I was only expressing my opinion having installed flow 90 fins on a regular mirage drive and using it (I'm a mechanical engineer and I think thru this junk).
FE

i try to put this subject again on top just to know if there are other people (except FE) who used the mirage Eclipse finns in the island
I would like to know how much harder is to pedal with them and if the cables of the Eclipe drives are stronger than then one of the standard AI
causing a weakeness on the system could not be worth.

thanx in advance.
