I used regular shorts for quite a while and then I got talked into buying a pair of bibs. Stopping for a nature break is definitely more challenging (and, really, pretty annoying), but I found the bibs to be a whole lot more comfortable. Having said all of that, I've been thinking of going back to regular shorts for a bit, just to confirm. My abilities and physique have changed a lot over the last year and I'm curious to see how regular shorts might fair now.
