I need a micro pulley for my lanyard, and there are so many (too many?) out there to choose from. Can I get a few recommendations please? I don't need anything fancy, but would like something relatively inexpensive that works well. setup is 1/2" line with VT made from Pruissik cord. setup is one rope snap, carabiners on both VT and other end of lanyard. Are there any other good ways of making these lanyards self tending?
