If you're happy with the tyres try them on the Buell............doesn't matter what others preferences are as everybody has their own views as to what is best .
Conti Road attacks are also a good choice and have had 5000 out of a rear on the X1 .
Like you say though tis easier to guage tyre wear if it has a tread pattern across the middle

If the Metzlers work for you and you are happy with them, then stick with them! Ignore those who say otherwise, you are familiar with the characteristics of these tyres, so stay with them.
I have Michelin Pilot Road 2CTs on mine, and I'm happy with them. 7,000 on the pair so far, but I'll be fitting a new rear before I go to France in July.
If it ain't broke, don't fix it!
