I'd say that it comes down to the Ensigns, the Indian-made Dunlop Uni-Grips (which can be a bit difficult to find in the UK although I think Draganfly have had them) or the Dunlop K70 which is more of a 1950s tyre but is undoubtedly a very good high-mileage serious rider's tyre.
I've got Uni-Grips on (the Ensign's weren't around) and I'm happy with them - they're round, black, look the part and have given me no nasty surprises.
