Here's the 250 year old red oak where the swing will be. I'm going to stabilize the the branch with some dynamic cable near the end to minimize the shock load, and tie it farther up somewhere (better safe than sorry). Looks like 3 strand gets the vote.
Up for suggestions, I'm looking at 5/8 double braid for .70 per ft. I don't think I want to use manila or promanila. It's going to be a single seat wood plank style.

Willing to commit fraud to get rich and know you'll get away with it may not be lazy but kinda dickish...don't you think? These are the banks I think Mac is referring to. Ahh... morals.
Just getting back in the sadddle again myself, mentally and physically. You have my sympathy, what Treehumper said, plus stay positive, that was the hardest part for me. I pretended everything was hunky dory but things were not. Keep us posted on your progress if you want.
