Bri, i like overpowering and lifting too, building a boom from the tree's structure, and powering it with overwhelming force, plotting the stob end as heavy, and notching on top. In betwixt lifting and lowering, i have found pretightening (and sometimes then selftightening) the line hitched at a specific point on the load for proper leveraged balance (yet positive 'nose' weight) to slide and move the load sideways very comfortably, spinning it around on a wide open, perfect hinge (while pusing all this as far as possible tweaking, i found that making a perfect hinge, with no crossed lines, at an angle it can function at is one of the most important things); then letting the green (heavier)end tip down into the open box. It truly takes the right hinge, anchor, and hitchpoint on load; but what a poewerful, graceful machine working right! Glass might be a more expensive structure to work over, but i think less forgiving than the floods of screen and light aluminum that we foster down here, not necessarily stuff for a junior climber don't ya know!
Bushings take more abuse but are less efficient than bearings, but that inefficiency is somewhat overcome in the larger sheaves, for the larger sheave (at rope tread) to 'axle' diameter, the more mechanical leverage the sheave has on it's host, making up for this inefficency.
Another good thing about pink paint is that my color blind guy sees it better in the grass than red/orange/green! i try to use bright, 'don't lose me colors', have been through the 'neons' (green, orange etc.); pink seems to be it. Besides, i laugh about JP giving Tom a hard time about it, thinking know macho male would take, 'con-fuse' pink as there own (hell, that don't even work with lighters!).
i like having gear that i am familiar not only with it's use, but history; feeling that both present a safety factor, that goes for metals and synthetics!!
