My first tires were PR2(good)...never felt totally confident in the dry , even less in the rain.
Trip to the Dragon in May...SHINKO 011 VERGE (awesome) ride up and (awesome) grip and feel on DRAGON and highway
Big hole in rear Verge 11 (750 miles) Still on vacation at Dragon and three car tire plugs would not fill the hole
All tire place had was PR3. PR3 (great) but not awesome... Not quite the grip or feel of Shinko but much better than PR2.
These are my findings and I am sticking to the SHINKOS. Your opinion will probably be very different.
