Has any tried the Heidenau K76 tire on a GS? It looks a lot like a Tourance (might be some similarities). I'm shopping for my next sets of tires and would like some feedback from those who own, have tried or heard of (a friend) who has them. Of course, it come in our size! http://www.moto-amore.com/heidenau/productsnew_b.html right next to the K60
