If you do purchase additional stops, you might want to also get an additional hinged guide rail bracket such that you can leave the hinged bracket mounted on your guide rail. Reason being, that if you remove and remount the hinged bracket, the alignment may become off slightly when you remount your rail as there is a little play and you cannot guarantee that you will remount the rail in exactly the same position. At one time I have had three hinged brackets mounted on different sized rails, one for each a FS1080, FS1400 and FS1900 rail.
Also, you may want to consider moving your stops to the other side of the brackets. The MFT comes with the stops mounted to the left (back) side of the rail which requires you to feed the bracket into the side profiles from the further end. These stops will work on either side, so long ago I changed mine to engage the brackets on the right (cut) side of the rail. Much easier to feed the hinged rail with attached guide rail the shorter distance.
Lastly, if you have low ceilings which don't allow you to have your rail tipped in the upright position, you can simply use a board to support the rail when in the upright position. I keep a 24" long piece of scrap on top of a short stack of Systainers beneath my table for just this purpose.
