Despite the fact I have just completed my headband set up (see thread), I still crave attaching a T20CS to it. Does anyone know if a) a T20CS would fit the fenix headband clamp? or b) what the diameter of a T20CS is at its narrowest point in the middle? Their website says the tail is 25.4mm but the middle looks narrower and if it was 23mm it would fit. Still might be too heavy though as the D25LC2 is pretty light weight.
