I use Tourances andlove em to bits. Had a bit of a moment the other night (very cold and just a bit slippy

) but they slid very slowly and controllably. Let you know with a very vague feeling well before they let go. Anything after the TCK's will be a step up in handling. I've ridden on TCK's and liked em for their looks and the dry grip is actually very very good (had a few fine ride outs with em and suprised a few people I'm sure

). However, in the wet they can step out very early and very quickly, got rid of mine after a couple of "oh b*llocks" moments and a "This is gonna.................ooooh ya B'stard" moment. My life flashed before me and I realized I hadn't done enough yet. Next day had Tourances fitted and life is groovy once more.
Try em. If ya don't like em and they slide around everywhere, bin em and try again. Unlikely that they'll be bad and most of us would struggle to tell much of a difference in grip. Most tyres now are ok it's just some give an individual confidence. I love Tourances and would be loathed to change but I may try the Pirelli tyre that is a bit more off road than the Tourance but more on road than the TCK's.
Give em a go, if you don't off road they'll be better than TCK's.
