Ahh that was you? Thought the name seemed familiar.
Can confirm, TT20 & M2R Pro will be a bit big, easy to get stuck in a bag.
Olight S1R II is absolutely tiny and gets hot after a few seconds on turbo andwon't last long.
Olight S2R II is a better size with almost the same output, but bigger battery and form factor, so it's better to hold, but only has side thumb switch.
Olight Baton Pro is slightly bigger than the S2R II and is a floodier torch, but twice the output up close and a great all rounder. Again, side switch only.
Klarus E2 is damn nice and I want one for my EDC, but have never used one sadly.
Warrior Mini would be the best bet of the Olights, if you can find one. Tail Switch and small form factor, perfect
This is the S1R II compared to the S2R II and the Lumintop FW4A (Which has an involved UI and not a good pick for tactical defence)
