That is really looking sharp!
I have not flown a 1/2a c/l in over 30 years (or any other size c/l for that matter). I think I used to glue a nickle to the outboard tip. I have no clue if that was right or wrong.But worked at the time, but I dont think I flew on much mare than 30-35 foot lines.
It looks like yor leadout guid is adjustable, nicely done.
