I've never seen a live Heritage, but it would be fun to try one - they look beautiful and I only hear great stuff about them. I really like the Kat and have had it for quite a while now, and it has always survived herd thinnings. I like the P-90's - they can play clean or crunchy and can sound like single's or almost HB's. I also like the feel of the guitar, and love the Bigsby. I did rewire it with lower impedence cable based on an online suggestion as they are a little dark sounding, which made a nice improvement.
