Raddo,
Let me make your life a lot simpler, when building a FasTrack layout I now custom cut FasTrack pieces, to any angle & length I desire, using the Rockwell X2 Blade Runner portable table saw, this incredible saw makes perfect cuts on FasTrack at any angle and length, you will ever need. In this manner your close out pieces will never be a problem again. In 10 minutes you have a perfect custom track piece, eliminating all your close out design problems. Purchase the X2 Blade Runner at Lowes, if you are a Military Vet, total cost $89.00. If you make FasTrack layouts all the time, it will be one of the best investments you ever made. I use mine all the time when I re-design my FT layouts, especially on the 2nd and 3rd levels.
