I always use 150 becasue I like the extra control for muni, drops, hops, stairs ext. and when I want to go fast i just have to kick my heel Right now i have a WTB ExiWolf on it that I got for free (used) from the LBS. Its a lot better on the road than the Kenda I was using but the sidewalls are thinner.
Yeah, I had a nanoraptor on my old 29er, and it sucked offroad! The sidewalls were way too thin and it felt very odd on anything that wasn’t smooth. I am looking for a good compromise between the Navegal and the big apple (if I ever switch my hub back to a 29er).
