Hey Marshall, for the pull-pull, I am using 'SpiderWire' fishing line. I believe a spool is about 7bucks, and I am using the 50lbs test. The stuff is tough, but does fray if abraided, so I went with the ultra heavy stuff. Still much lighter than any hardware available anywhere. I CA it to the dowel control horns after wrapping it around the dowel about 6 times, and I use a little kicker on the CA. At the servo end, I capture the line under the servo arm screw.
Derek, if you can't find spruce at your LHS, check a Hobby Lobby craft store. Interestingly enough, my LHS doesn't carry spruce, but the local flower and basket place does: ) If you can't get the spruce, the basswood should be fine. Just remember to build light.
