TWS,
As a note, almost all well made waders will roll down. The suspenders should have inverted buckles so that they become a belt.I'll go with the Dan Bailey waders as they also fold down to waist waders when conditions allow and have a good reputation.
ps ... I use the Chotas too and like 'em very much. Medium support, light, speed laces.
