catalina27-talk: bosun's chair alternative

[sailrmann]

I have ordered a petzl-corax climing harness to replace my (recalled) buson's 
chair.
Apparently some of you are knowledgable about climbing. How does the GGG (Gonzo 
Guano Gear) Frog system compare to Petzl Frog Ascending system, the rope 
walking system and ATN Topclimber?
I suspect the Topclimber is the marine version of the rope walking system, but 
don't know.
The ATN Topclimber is about $324, the Petzl Frog System is $177.50 at 
kartsports.com (but needs a harness, which I now have).
