I was not looking to do a lot of research on this (sorry :tinfoil, was hoping someone in the know could clue me in. I am looking to get a back-up LE for my D10.....I love this light, and would be bummed if it crapped out and I couldn't find an LE for it. Has the D11 LE been upgraded to the point that is is worth considering? I seem to remember it had parasitic drain issues? What would you recommend?
