Just climbed on my new PMI Pit rope with a RIG. I must say it is way smoother then hitch climbing! Unreal how easy it was to take up slack/let out and move around the canopy of my large Pin Oak. Also a big plus that Pit rope is very abrasion resistant. This is a rope that PMI has made there main stay for caving for a while now. Would have to give this rope with a RIG a huge thumbs up!!
