Looking at cutting down my equipment carried and have never had an occasion to use my come-along. Anybody with a lot of experience with z-drags? I have used them a bit using just carabiners as a pulley. How much better would real designated pulleys work? I have found carabiners work ok with slick rope and 3-1 ratio. I wonder if pulleys would be much better and worth carrying. If so what is a good source?
Biggest problem I have had is rope stretch which can be a problem with a heavy load. Other than the expense of a Spectra line are there any good slippery synthetics that don't stretch much?
