From the report:

Once above 2000ft- I started to gently experiment with possible
solutions - the climb gave me time to think it through - and generate a bit of a
plan. There were 3 options.

I had a hook knife and provided I could reach to the boot of my harness I could
cut the line.

I could also pull the zipper tab - with great effort as I had to lift the dolly
and get to the line or knot - that would take 2 hands but at least was
theoretically possible.

I could also use my chute.

Since we were still climbing, and I was in control I tried to think through the
consequences - if I cut the line in the wrong place and it hung up again and
jerked the glider what would happen? - could I reach the boot? What would happen
when you unload the glider by 100lb suddenly? Should I release then try or stay
on tow and try?

I also was trying to see what I could reach - which tended to put me out of
position but gave me a good idea what was possible, and after some rehearsals. I
was feeling fairly confident I could shed the dolly - we were at around 5000ft
by then.

My plan was - try to hook knife the cord at the boot - if not then release and
use 2 hands to cut the knot at the draw tab and if I ended up below 2000ft, pull
the chute.

The first option went without a hitch.
