I'm out of practice in these and I want to work on efficiency for some El Cap ascents next year that I should have done in 2014. Serious & reliable practice partners welcome, but I'm also plenty happy to rope solo, set up fixed lines, etc. I'm not very familiar with the Denver crags for walkoffs to good cliffs/anchors for stringing ropes & hanging out for such practice (low angle & free hanging jugging laps, hauling/portaledge hanging anchor fun, etc.), without also getting in the way of others. Ideally stuff I can squeeze in on weekdays in the mornings or evenings coming from Broomfield.
Sadly aid/big walls seems to be not much of a thing out here like it is in SF or SLC based on my current findings.
North Table generally has easy top access and is good for this sort of stuff, the heat won't be fun but it will mean that you'll have it mostly to yourself. Ugly Stick at Winter Warmer wall works as a 2 pitch practice route.
There are a few real aid routes strewn about in places like Upper Dream Canyon (China Doll), but I'd recommend just heading to Moab to get your real aid fix. DM me if you're interested on exploring some of the aid around here, would be happy to partner up and practice.
