Hey John,
I’d just get alloy screwgates for the anchors and master point. They are lighter (if that is a factor) than steel and whilst steel can usually hold around 35kN of force, no fall is ever gonna generate anywhere near that, especially on a top-rope. And they’re also cheaper. Just have to watch them for thread wear as the alloy is easier to deform. The ones with a little and a big end are best (HMS??) as they are a bit more versatile and can hold more than one rope comfortably.
Ummm, I prefer using static rope to set the anchors up. Sure, use tape and slings to go around trees, etc but for the actual runs to the master point I prefer static.
And I guess it goes without saying that you should use two biners for the master point, in an opposed setup to prevent the rope escaping (rare yes but it does happen).
Maybe I’m starting to state the obvious here but just tryin to help out a friend. =)
P.S. – Anita and I have been frequenting Churchman’s if you ever wanna meet up for a day on the rock.
Cheers
Ben
