I've read where people are using dynamic rope as a tether. Is this useful, or just stick with the Samson Predator? I don't have a tether and looking for one. I will be climbing with a LW hand climber seat and using it as a platform. What would be better when using the tether for climbing, Ropeman1 or prusik or both? I'm using an Aerohunter Evolution saddle with adjustable prusik/opening with carabiner bridge.
