The Avon AM26 tires are a bit low profile but look ok. I'm limited in my choices here on a small island but can get these online.
I tend to use these on all my bikes. They wear very well, and most importantly, are sticky in the wet (it rains very often here). Have not done enough miles on the WM20 to comment on their suitability but I have a friend here that uses his WM20 on a very regular basis. He runs AM26 tires too and swears by them (the main reason I got these).
