I'm completely new to Festool. I just bought a TS55 REQ track saw. Right now I only have the 55" track that came with the saw. From what I understand joining multiple tracks doesn't always work too well. Since I plan to break down 4'x8' sheets of plywood I will need to get a longer track. Should I get the 106" or the 118" track? Are there any advantages to the 118" if I only plan to work with 8' wood?
