I think that is what I'm goin to do. I made a list of
things to get. I decided no buying two right hand
ascenders instead of one of each--based on advice
I found online.

As I have wire halyards, I'll have to either change
one over to rope, or else plan to add another halyard
to the mast.

In either case it will be easier to go up with one helper
rather than the team of five I use now.

Never used one of these but climbed many thousands of feet on rope in
caves using a similar "Sit-Stand" system based on Prusik knots. To get
down, you reverse the process. You could make your own.
