I start off new climbers with all of my gear. The nice saddle, the uni, the pantin, the nice rope. I have them climb like this a couple of time then I take it away and teach them old school.
It's important that they know that there is a light at the end of the tunnel, a very expensive and difficult tunnel. It is also important to evolve into the new climbing systems and set ups so that they can understand how they work.
We've got a new (well, actually he is 40) climber that is just learning how to climb without spikes after spiking everything for 21 years. His first time out I have him the goods. Uni, foot ascender, hand ascender, ran him through a ring and ring. He kicked his way up 20 feet, worked the lower portion of the oak tree then ascended down. That was the last times he has ever seen my uni.
The next time, gave him my beeline eye n eye, my extra hitch climber, my poison ivy line and foot ascender. He worked a smaller maple.
Next time. I had him climb on his true blue, blakes hitch. Made him climb like he had for 20+ years but without the spikes.
A week later, he owned a new eye n eye split tail, hitch climber and foot ascender. Next week he's buying a cougar saddle.
This is a bit different though. He had almost more experience climbing then I have living. He knows the oldschool ways. I thought that I'd show him what advances had been made since and let him decide what was best for him.
