Two quickies for people with experience: 1. Can you tell me about the new liner-less waistbands vs the lined ones? I hav experienced the lined ones, which are 1.5mm thick, but not the new unlined ones that are 3mm thick... differences? pros/cons? 2. The snap lock vs the abus locks. How pickable are the snap locks? and is it worth the trade off to get the slimmer profile? thanks.
