K-7 gets my vote. I've owned since new for probably like 18 or 19 years now. Soon I'll be putting the original PAF-7 in the bridge and taking that crappy X2N7 out. It needs a good clean and possibly a fret crown and polish too.
My RGD7UCS. I wish they would do another run of these with a flamed maple top. The fretwork/stainless steel frets are immaculate. I also love the aftermaths.
