I've got an old 10.5 infinity (can't remember which model), has served me well for the last 3 years through a fair bit of falling off stuff and shunting trad routes back at avon. Just got a new 70m tendon master 9.7 for long euro sport onsighting shizzle, can't give a durability review having only had it since christmas, but liked it on a trip to chorro over the last couple of weeks.
