Re: Lil '59 vs. Cool rails
Having not tried them side by side, I have noticed that both pickups take a Fender style guitar and make is sound Gibsonish.  On my Squier, I have the Lil 59 in the neck position.  The poles are spaced slightly wider than the strings, but with the Lil 59, you can adjust all 12 of the individual poles to make them sound right.  What I like about the Cool Rails is that the blades are already curved/radiused nicely, so a little adjustment of the total pickup height usually does enough for me.  Also, I like that full output on string bending with the Cool Rails.  On the issue of signal drop with string bends, it is most noticeable with the Duckbucker I have in the middle position.
