Here we go again...spine or no spine...it's a no-win discussion. On my 7-piece Forecast I built it for straightness, and when I check the spine (just for giggles) it was right on the money with the straightness. Funny how that works sometimes.

To get to your original question, the most important thing you need to watch for is to be having fun. If you get frustrated with any step in the build process, walk away and take a break. It really helps. Oh, and don't be afraid to call for help. We're all here to make sure you have a successful build so you can become addicted like most of us are.
