i agree, my favourite neck pickup is the Mini humbucker in my Les Paul Deluxe. in an ideal world it would have a full size 'bucker at the bridge, but i'm not routing out a 40 year old guitar!
i'll reiterate, your group of PRS guitars is stunning, Dave. i'm glad you've found yourself in a position to be able to get them together, and it's obvious how much pleasure you get from them. we all know that however satisfied we are with our gear, eventually something appears that tempts us! but i think it might be a little longer than usual before you're showing us your next baby ;)
