Actually, my favorite is the RG2420-TB right in front. It's got my favorite wood combination (mahogany/maple), pickup combination (Tone Zone/PAF Pro), and neck profile (Ultra). Plus, I'm {obviously} a sucker for anything with flamed/quilted maple tops, and the 2420 has a quilt so deep it looks like you could go swimming in it:
My second favorite, after all these years, is still my JPM100-P1.
