My Boardman 29er came with OEM Knobby Nics Performance Line. They are not labelled as TL, but they were the easiest tyres I have set up TL. They have stayed inflated and sturdy.
Good luck. What rims, tape and valves are you using?
I find the superstarcomponents tape cheap and reliable (only tape I have used), their valves are OK, but recently used DT Swiss valves and the are a very good quality and nicely designed with an additional rubber o-ring to seal at the rim hole.
