I haven't been to it personally, but from the map I can see it would be a heck of a tough pull-down. It has a 241' pit about 1/3 of the way into it, and a total of 6 rigged drops. If you rig it for a pull-down, (at least the way I rig a pull-down), you'd be hauling a 500' rope through a lot of very difficult cave. It is a really wet cave as well, and there's a reason they call it "Bloodstone."
Perhaps some of our other regulars can give you a first-hand account.
