For the last ten years I have used metzler's, not counting OE tires when bike purchased. I have yet to experience any of the wobbling complaints that some have reported, maybe just lucky. I like the way the metzler's handle, especially in the rain. Also, around here we are blessed with several bridges with steel grated decks and the metzler's handle that just fine.
The set I have on my "Silver Lady" now have 17,520 miles and are still street legal. Normally I would have replaced them before this, but I have been waiting for that front tire which I just got last week. Tomorrow I get my bike back from the dealer from it's 32K & EMC upgrade and then the tires get changed, to metzler's again.
A few years back two of us rode the "Four Corners of the USA", a trip of about 11,000 miles. We both rode solo on identical equip Honda PC800's, except for the tires. We both started with new tires, me with metzler's and my partner with new Dunlops. Same miles, same temperatures, same road conditions, proper air pressure. At the end his tires needed replacement, mine were only half used up.
