Yeah the Shinko does not look too round. Really don't know until you ride it though. I spent $2000USD for tires last year for two bikes, so for me it may be a trade off, I need to ride everyday and the treadlife is my priority over leaning over as if I was Rossi.
The roads in Mexico that I travel on are treacherous, mostly pavement but still full of potholes, rocks, and all kinds of sharp stuff that can slash your tires. Tourances run about $300 each here. I rather throw away a $70 Shinko 705 with 1000 miles on it than a $300 Tourance with a 1000 miles.
I'm still interested in the Heidenau K60 though. More aggressive tread pattern and I guess I am brainwashed about Euro tire quality.
