Scott,
Haven't had a chance to visit the Ponderosa Course in person, but a quick google pulled up their website.

Looks like a fairly nice course to me. I like the idea of platforms that need no tree penetrations, but I do have to wonder just how they're hanging these platforms, as it's not visible in any of their pictures. Their cableways are hung in a pretty standard method for tree-bound ropes courses, using multiple wraps and a collar made of spaced wood blocks, visible in this pic.
I also dislike the fact that there's no backup to their cableways. The only thing the climber is clipped into during the traverse is the Petzl TRAC pulley. Truthfully, this is an issue that's going to nag me until I give up rope altogether.
I've been involved in so many different forms of climbing (Sport, Trad, and Aid on rock; ice, canyoning, spelunking, painting water towers, rope rescue, challenge courses, and of course, tree climbing) that the different rules of thumb and standard methods I've learned may be mutually exclusive or downright contradictory. Tyroleans/traverses/etc are one of those things with many many "standard" and/or "accepted" practices. Which one is right? Lol, Heck if I know. I get grumped at by my rec climbing friends because I'm slow, methodical, and in their opinion, way too dedicated to safety and good anchors. On the other hand, I get grumped at by my rescue and industrial compatriots for being too cavalier and not concerned enough about anchors and redundancy. Can't win, eh?
