its all personal preference mate and all this 180 handles better than a 190 is ******** for road riding IMO
as for the T handling better on skinny tyres - its more to do with the profile of the tyre not the width
having rode the T on a 180 and 190 back to back theres no fookin difference and its all in the mind
I have seen and heard peeps who run the 180 wax lyrical over the amazing handling and still have a 10mm chicken strip each side
easiest solution is replace like for like as that's what you will be used to
