I've got Lows on and BigApe and Sid Squid have got Ultra Lows. I much prefer mine to theirs and vice versa

. So it's really a question of sitting on a bike with them on and seeing what's best for you, and the best way to do this is find a busy bike meet and seek out a bike or two with Renthals and start chatting to the owners explaining the situation and I'm sure they'll say hop on.
But in a nutshell, if you like being really upright then the Lows are perfect but too high for most riders it seems. You'll also have to be very watchful of the cable lengths as they only just (on my K1) stretch far enough.
