Climbing the mast
Hi, I also love my Top-climber. I also get to the top while standing,but it''s hard to work standing unless you tie yourself off some-how. I do not attach a climbing line to my halyard. The resulting knot keeps you from climbing 3"-4" higher,or more if the rope stretches. I installed a designated line(halyard) for climbing without a fitting spliced on the end. It''s always ready to go. The line that hold the seat has a snap shackle on the bottom of it. When you get as high as you want to go, you can raise the seat about a foot higher by snapping that shackle to the ascender handle,or to anything at the masthead,such as a eye bolt,a ring,a hole,etc. Then,when the seat is at the correct working height, you hands are free.
As far as changing the ascenders for Petzl''s.The cams on the originals are smooth & much easier on the rope. The Petzls''have sharp teeth.Both hold equally as well,once weight is applied, but the originals make descending much easier.
