Thinner = better riding performace, but larger bearings outside (read: thicker) last longer. Many super-light pedals use a bushing VS a bearing or micro-bearing. Minimal longevity there.
So you should consider how soon you'll be likely to replace them. Some expensive pedals, like many HT offerings, use bushings. Some less expensive ones, like DMR V12, are virtually indestructible but use a full-size bearing on the outside. I used PointOne Podiums hard for a few years and destroyed the micro-bearings in both pedals. I just got a complete bearing set for these for $40; better than a new pair at close to 200.
You can change the grip of any peadal by changing or modifying the pins. HTs seem to have long pins which break off relatively easily.
Just grab a pair for as cheap as you can. Go used or take-off. When those go tits up, you'll have a better idea what you like in a pedal.
