I've also got an AM26 on the rear, and I have a TT100 on the front. Not bad in terms of stick, but the profile is indeed a bit low and you notice the small change in gearing, certainly compared to an Avon SM.
I had a TT100 on the rear too, briefly, but it lasted no time compared to the boring old SMs I'd always had before. Quite sticky though, when it was young.
I'm in several minds as to what's 'best'. I have TT100s on all my other 19 inchers at the moment, following a visit to Vintage Tyres in Beaulieu when I filled a car up with the things. They stick quite well on my 650SS Norton (decent handling) and on a 650 AMC twin (less decent), which are both quite a bit more powerful than my A10. But they are wearing out . . . . quite fast . . . . just as Black Sheep describes. That said, think I prefer them, so far, to the Roadrider, and I'm not sure what other choices there are out there.
