Just my opinion, but I have already seen ‘mini’ and ‘micro’. ‘nano’ would not add too much value - especially, if I take a look at the original name (‘Giga Thrower’).
However, if a variant with d = 100-105 mm reflector would be built (let me call that GT M), with a reasonable size and net weight (let me say <0.85 kg) and with 4×18650 or 3×21700, I think, that could add extra value to the GT scene.
(If that would happen, maybe there should be both XHP35 HI and White Flat variant)
i have a mf02, uses 4 18650 and is super heavy… barely using it, i think a ft03 clone with 70mm or bigger reflector and takes a single battery would be better , 21700/26650.i think its good they do more variants on the GT series, some like big some like smaller, we all have different needs and wants so its nice there will be a selection of different i guess this isnt the last one we will see…
