RE: q on isonic and sails
Thanks, I understand, will test with smaller fins first.
I agree with your opinion about the small gap, that's also why I was loooking for input from others, like, does a .5 gap difference really extend the upper level enough ?
There was once a rule of thumb about app 15%, now that would mean that I should be looking at something in the 4.8 range. But was just thinking, and maybe even hoping, that it could be pushed to an extent where the 5.1 could do the job.
