Keven, I've never used any mounting device at all. I use Gepe double-glass AN mounts (Art no. 6002). To mount the slides I simply use a pair of tweezer coming from my Victorinox and my fingers. Just apply pressure with your fingers to snap the two halves into place. Check along the sides to ensure there is no gap to make it quite dust proof. I wonder if the slide mounting device will make the task much easier.
