Re: Mast work
In my group of friends we all have a ATN Mast Climber that we use and share. It's so much easier for the person going up the mast to use their legs to get up there.
The Mast Climber is expensive, but building a self climbing system myself wasn't going to be that much cheaper (maybe saving $100).
I don't know what ATN's weight limit is. We also back up the Mast Climber with a second halyard and someone tailing it on a winch just in case.
