Do you guys and gals have any recommendations for a rear tyre for the 456 Evo II frame, as my Advantage 2.4 is coming up a little large in the upper chainstays and what with the gloopy wet weather coming, I think something a little narrower/less tall might be useful.

Preferably I would like a folding bead tyre to save a little weight, around the 2.2-2.4 size - however, that can vary hugely between manufacturers/models so real world experience would be useful there! If it helps, these will be fitted to a 521 rim.

I've been browsing the 2.25 Ardent/Advantage but according to Shiggy's database these are only marginally smaller IIRC. The 2.35 High Roller also looks promising but is a little 'undersized' more comparable to a 2.1 and the 2.25 Crossmark, though this could be a little flat/less grippy for the mud. There is also the 2.25 Nobby Nic, but finding any info as to how well these compare to the others in terms of size has been a bit difficult.

Thanks in advance
