I definitely recommend the 4 bladed easel, the vt1400 is the V-Track right, I have one they're nice. So here's what I do. First I sacrifice a sheet of the enlarging paper, then on the back I carefully layout and mark my borders. Then I put the paper in the easel making sure that paper is positioned all the way in the slot and slid to the left hand side. Next I align the easel blades, with the border lines I marked on the paper. I also use the paper composing and focusing. When printing just make sure that you position the paper all the way in the slot and slide it to the all the way to the left. This method will give you very consistent borders.
