KMP600 started out as brushed with polished stripes. I liked it in theory but I was never very happy with it. Later I brushed the stripes and it was an improvement but looking back, all brushed would have worked out best as far as no paint options go. It's a badass look.
All polished Kirkhams are beautiful. I'm glad folks have them but they're not for me.
People said I'd hate the black finish but I'm loving it. The little scratches buff out really easily with Griots compound. Nothing looks better than black too, IMO.
Any way you slice it, you can't go wrong.
