RE: SpiderWire
I really like the braided versions of Spiderwire better. Knots are important but the plane you mentioned isn't going to put a lot of stress on the knots. The palomore may be best but several good fishing knots will work with a light 1/2a. Be sure it is a good knot though. Carelessness at this point could wreck a plane and a bystanders day. I use 20lb test/8lb diameter, but smaller line would be ok. I wanted line strong enough to hold a heavier plane with a more powerful 1/2a engine. At any rate, I think spiderwire and similar products are far superior to the old stretchy dacron lines that came with many 1/2a planes. In fact, I like the spiderwire so well that I may even try it for fishing.
