Like you, i've been meaning to make the move. I like both the black and white. BK offers both but i cant quite decide which to go for. Personally, for whatever reason, i just cant see the grey rings for the black (perhaps im just that kinda guy who cant see the forest for the trees, nor smell my own sh!t on my knees)...
Anyhoo long story short, ive got both the black and white gen dials albeit the tritium versions...but alas dunno if they'll fit the noob ones that BK stocks coz like by-tor has said, onlythe older seemingly extinct versions seem to be able to accomodate these....
Also my white dialed one is a little banged-up...dunno if shld get it relumed etc....
You think your head's spinning? Mine's practically falling off
