I'm one of those Avon geeks... been hooked on them since 1998 when we got an Avon sponsorship for our roadracing 'team' (if you can call a bunch of friends who carpooled, a team.. lol). At the time, the tires were NOT track capable, got slicker than snot (overheated) in a short time because we didn't know they required more air pressure. So we bought a load of Dunlops for our racebikes and just put the Avons on our street bikes (or rather, *I* did because I was broke, and they were sitting in a pile next to my only means of transportation.. a motorcycle).
Once I played around with the tire pressure and got that sorted, and noticed I was getting 8~10k from a set on Hard street riding and daily commuting, the others snapped up their shares. :P
I keep trying other brands, but nothing compares (for me and my style of riding) to the Avons (first the 35/36, now the 45/46) and I keep going back to them. And they do have 110/17 and 150/17's available....
But tire choice is personal... I *HATED* M1's, didn't get even 3k out of them before they were trash, paid more for them and noticed absolutly NO difference in traction/confidence/ability. They were the darling child of the sportbike world just a few years ago (and I was well flamed on the ZRX forums for my comments about them).
