So I'm getting a new TS 55 REQ in a week or so and I know I'll be doing some 8' plywood cuts and even some angle cuts making that even longer which makes me wonder do I need bigger than 106" since a 4x8 sheet is about 107" corner to corner? I've never used one of these before and am wondering if I should get the 106" track or another 55" track and join it with the one I'll get with the saw. At almost $300 For the 106" I need to make sure it is worth doing. Can I trust that joining 2 tracks will give straight cuts and does the saw ever jam or skip when it reaches the point where tracks join? How quick and easy is it to put 2 tracks together? Sorry for all the noob questions, just trying to get the most from the new saw without tossing money unnecessarily. Thanks in advance for any input.
