Hi Davey,
I live here in Ouray. For climbing in the park 60m works fine top roping. I use a 10mm rope for durability. for leading anything else in the area, and you should check out all the great climbs outside the park, 70m half ropes are highly recommended. most routes you need to rappel off.
one other recommendation is to buy a 20m section of 9 or 10 mm static line for setting up your anchors in the park. last year many trees had to be removed for beetle infestation and concrete anchor pads were installed. a short static rope makes setting up TR anchors clean and easy.
once your here feel free to stop my shop, alpine Luddites, www.alpineluddites.com, if you have questions. Ouray mountain sports, our local gear shop, is also a great place for information once your here.
