In this case, I would prefer the L6 style. Switch is on-off (that is a forward clicky, if I am correct), and an electronic switch for the UI. If there are enough space in the tailcap, they could be next to each other, or if it is possible, the electronic switch could be a ring around the on-off switch.
I am very used to change mode after I have turned on the flashlight, maybe this is why I hate forward clicky.
ToyKeeper already proposed to help but it seems that it has remained dead letter and zero progress was made with Convoy’s flashlights UI, maybe Simon prefer to do things in his own way or maybe it’s because of people continuing to buy his drivers that he doesn’t see the point to improve UI, while better UI would make them even more popular. Bistro UI at least for clicky, please !
Bistro looks too complicated to me. Also Biscotti has too many options, but I select one mode, store it, and that’s it. Actually I liked the old 3/5 mode driver, except that it generates a squaling tone, which nobody likes. Ideally I’d like to simply have 4 modes 3–35–70–100 no blinking stuff etc.
