im new to tree climbing and right now am using some rock climbing gear to climb trees with. i am slowly getting the arborist gear, but right now i am using my rock climbing harness, safety blue for my split tail and blue water rescue rope. https://bluewaterropes.com/product/12-colored-safeline/ i have climbed a dozen times without any issues. the blakes hitch on my split tail on this rope holds great and releases when i want. the only issue is tying in the blue water rope to my caribeaner. its a very stiff rope. is this ripe ok to keep using? it seems to be holding up great and i believe is stronger than arborist rope. i think its to stiff for a taughtline hitch, so i used a figure 8 followthrough and it seems to be ok. and when i tryed using the rope in my act or tubular repel device (i think thats what its called), just getting the rope in the device was a little difficult. can i still use it or should i run for the hills until i get an arborist rope? any input would be very helpful! thanks!
