Took big betty's to the Alps this year, and in the dry I thought they were awesome. I like the fact they come up big, as per the name. A couple of times there was light rain which made the French mud greasy, and I was all over the place and off a few times. Wear wise, there is quite a lot after 3 weeks of riding, but to be fair I was riding most days. Reckon there is a bit more life in them yet, but won't be keeping them on for winter. Just bought some wired MM's from bike-discount.de at a stupid cheap price (circa £30 each).
