If you don't want to use Al's pulley system you might at least choose the Amsteel rope to save a lot of weight and bulk. The Amsteel will certainly not water log nearly as bad as the PSR ropes. You will need one 150' length and can probably get by with the oops bag rope perhaps only 100' long. Amsteel comes in many diameters. Al suggested the 7/64" diameter which we use. They make more diameters than you can shake a stick at. If you want 1/4 inch they have it. It is probably strong enough to lift two cars off the ground and may not be cheap. But it will probably hold up better than anything you will get at pricey REI. Do take note that you have to think completely differently about your bear bagging technique if you select a trek in the Valle. There are apparently no pre-strung cables. So you are back to teaching the boys the PCT or AT methods for those treks. You will have a great time no matter what bear bagging technique you choose.
