I have a torsion box type outfeed table (ala Paulk) with the 20mm dog holes that I made using the parf guide. I made a cross cut jig by drilling holes in some 1/2" scrap ply, drops into holes on the outfeed table. That allows you to have a zero clearance kerf and not cuts in your table, but more importantly it lets me located the track out past 3' to extend the width of my bench.
On the long piece I used an incra track as a stop block. The main reason being that with it's V shaped teeth I can drop right back in to the EXACT same measurement every time. If you ever mess up a piece later on down the process it's very easy to duplicate.
I was making some bookshelves and routing a dado instead of doing shelf pins (built in furniture look). The jig with the incra track worked great for this. I set up my router to run on a track, noted down the measurements I had used on the incra track for the first piece. For all the following ones I could drop the stop block in exactly the same spot, all panels came out dead on identical dados. No need to route prior to cutting the side panels and it allowed me to nest cuts on the sheet to get more yield.
For me with a very small shop currently going with a smaller TS fence and this cross cut jig really is the best of both worlds.
