i havent used a cinch for jumps but for belaying it locks off a lot quicker...makes it a good candidate.
am i trippin or are you using 2 independant tyrolean systems & joining them with a massive screamer for a lanyard??
whats your reasoning for usiing this over a single tyrolean with the limiters on the anchor? PM or email me if you dont want to post it up here (btw i completely understand and support keeping your setups out of the public domain)
