They are EXCELLENT tires, IMO. I don't ride anything else but Avons on my 750, after trying many, many other brands.
Pirellis aren't bad either, nor are Conti, but the AM26, both front and rear, make a stuck-to-the-pavement feeling underneath you. I usually run the AM26 both front and rear, but the pair you have chosen aren't a bad combo, either.
