Not really advise for aid practice in Colorado, but be solid free climbing Yosemite 5.10, 5.11 would be even better, then you will be able to free or french free the majority of the route. You will climb much faster and have a way better time then hanging in your aiders. Also make sure you are dialed on your pendulums and lower outs, some really struggle with the king swing and waste a lot of time. Don't take too much stuff or the hauling will really suck and you will ultimately bail at Dolt Tower.
If hanging in your aiders is your idea of fun, there are much more interesting routes on El Cap for that with easier hauling.

My goal this year is to do the Nose on El Cap, but I've never been aid climbing before. Can anyone offer any suggestions for some routes in Colorado this spring and summer that could help me learn what I need?
