Oh yes, I do regularly carry three lights. There's the Omicron, then I also have a MecArmy X4S (pictured in post 14) to act as a spare 10180 carrier, a field charger (from my portable USB power supply) and an emergency backup should the Omicron ever get lost / stolen.
When I'm wearing jeans (which is most of the time to be fair), I have either the Olight S1R, which you mentioned, or a Zebralight SC52d. If I'm on a longer outing, I'll also carry spare cells in a twist-tube carrier.
I like the idea of the field charger. Those little batteries are well suited to charging on the fly.
