Playing around with a new and improved lite, 'cuz everyday there's a new and improved model, I started to get bothered with the shadow of the barrel. I'm right handed and guess that might play into this? I think with all the tech out there that cords are pretty antiquated. But assume that currently there's not much choice unless you like a button? So, how and where do you like to mount your light and how do you like to activate them?
