Ti29er – can't really afford more than two tyres at the moment, so looking for a reasonably fast, reasonably good all rounder. My front Spesh tyre would give a bit of grip on the back on medium conditions, and I reckon would be fine on the front on really dry days. I guess it would be my own cheaper version of the Schwalbe three tyre setup.
Should also say that although tubeless sounds more reliable, if changing tyres for different conditions is better, changing tubeless tyres sounds like a right faff by the time you have put in sealant etc, and a spare set of wheels would be far too pricey for me at the moment.
Not ideal I accept, but thanks for the comments all. Still veering towards something around 2.1/2.25ish with decent puncture protection and inner tubes.
