It would be great to get some opinions on increasing tyre size - i currently use a Geax Saguaro TNT 2.0 on the rear and have been generally happy with the overall grip, wear etc - that being said this is in comparison to a crossmark 2.1. I use a Nevegal UST 2.1 on the front.

General blurb about the tyre is:
• Arrojo's natural evolution: same polyvalency and low rolling resistance. A tyre that nicely falls in between the Mezcal (dry, compact) and the Barro Mountain (wet, loose).
• Low rolling resistance thanks to the central uninterrupted knobs that enhance speed on compact ground;
