Like others I don't recommend cheap tyres , period. Life's too short to waste time recovering from accidents.
I agree about SMs - rubbish unless you like scaring yourself. My A10 has them courtesy of previous owner and they're coming off before it goes on the road this year.
Don't let them put you off Avon though. I'm going for AM26 Roadriders as I already have them on the Lav 750 which is much heavier (and more powerful) than the A10 and they're excellent..
Tried Metzlers, they didn't last long..
The old Velo has Avon Super Venoms & that handles better than anything with a frame designed that long ago has any right to!! Some people don't like the look of the modern profile but that's their problem.
Just another tyre opinion - you'll get loads of different views on this one....
