I've got all the variations of the hot/mod buttons, including TAPS and the Lites. All have been easy to actuate. the CLEANEST scout setup you will find is the Modbutton attached directly to the light. The wiring tucks away cleanly, wich is a huge bonus. I prefer the hotbutton, as it has a constant-on level, where the modbuttons don't. MLOK Hotbutton on the 11:00/11:00 is pretty awesome.

Also, while the modbuttons are easy for me to activate, they may be too easy. I'm in the camp that would choose a more determined action to activate the light, rather than make it so easy/light, that I get a light ND.
