Like you I've been reading and searching a lot around for the right info . As you I weight around 70'ish well it's more like 72 :-)
Anyway, I'm looking for a light wind board as well and I'am still wondering whether an Isonic 127 or an US would serve me the best as a medium weight rider especially I wonder if we would feel the difference a lot in the low wind area. For sure an IS 127 would be more controllable in gusts but the US width would help it plane faster .. but would make it a big difference ?
Does anyone out weight can chime in on this?
I'm planning to trade in my older board for a new one .. and I can't decide between an IS 127 and the US knowing that my next board is an futura 111.
