i have had an E2e with & without a GG&G TID, and with a KL1 head, and a E2D and must say my fav SF lite for edc is a E2e w/a KL1 head, i didnt like the TIDs on the E2e anyway, maybe on a Z3 or a M3, just made it too heavy for me, and the crenellations on the E2d i wasnt nutz about either, they are hard on your pants pockets, if ya plan on packing one get a belt sheath imho, like i say my fav is a E2e w/a KL1, #2 would be probably a std E2e, followed by the E2d, followed by the E2e w/the TID, all are good lites though, i dont know how much ya could do with a E2 series lite as far as the bezel strikes at least not without training, ditto w/the E2e w/the TID, they are plenty bright imho in either the std E2e mode or the LED KL1, very little dimmer than a Z2, a little larger/heavier lite.
i swapped the E2d and the TID i had , FWIW, after i put the KL1 on my E2e.
