I'm running into a similar issue that was brought up before with the Spring and Scarab. I purchased 31s and 32s for sizing. The 31s fit really snug in all places - but not uncomfortably. 32s fit looser - but the waist area just leaves way too much room. I have no issue wearing belts - but my fear is that the 32s would just stretch to a point where they are WAY too big.
I may wait a bit longer to see how some of us find they stretch after a few wears.
