There are only two things I do differently: I don't drag the tacking iron across the back of the print in order to prevent the tissue from wrinkling, and I don't mount the print then hope that I cut the window in the exact right spot. Instead, I let the tacking iron sit still in one place to attach the tissue, and I first cut the overmat, then center the print within it before attaching. I also have a Logan 750 and love it. The Fletcher 2100 is great if you can afford it.
