how to run a new main halyard in mast?

[quartersplash]

I completely rebuilt and painted my 60+ foot mast and resteped. Somehow when I reran the halyards (in mast), the main halyard got twisted around another halyard or the topping lift. My question is: What is the best way to re-run the main halyard? I was going to wait for a calm day and drop a nylon line with a weight to the bottom of the mast and then fish it out of the exit point of the mast....Any other suggestions?

I have tried the fishing line/weight trick twice, and it worked like a charm for me.
When replacing a fair existing one, I stitch loops to join the new to the old, end to end
and pull it through.

Two feet of bicycle chain + some small line. The chain can be pushed over the sheaves, where the fishing weight might refuse to go, trying to push on the line...
