here's my apex set up for daily use/abuse/commutes. i've got 2" big apples and sks fenders with tons of clearance left over. if this wasn't a parts bin build and i didn't just have the 2" laying around, i would've gone for the 2.35s, which is what i suggest for you. don't listen those suggesting a wide tire doesn't roll as fast - they do, and you'll be way more comfortable than you might be on 1.5".
