any comments to share on these?"

     Spicer mounts have an advantage in their range of apertures, too.
     The trimmed RBT method I use is a little different than on the Spicer
web page. Instead of slicing the bottom off the RBT horizontally and leaving
a sliver of the apertures bottoms, I cut the aperture bottom out completely
except for a little at the sides:

     After placing the chips on the sprocket posts, I adjust for the window
using strong reading glasses then carefully slip the RBT into the Red Button.
The window is usually OK, and the RBT has set the vertical.
     The Spicer mounts are scored to fold neatly and evenly in the middle...
I use this fold as the top in the event I might want to project so as to
avoid an uneven tape edge.
     With the mount folded at a 90 degree angle, I slide the RBT onto it so
the bottom chip edges are flush with the bottom of the cardboard mount(hold
the two mounts together with thumb and forefinger curled over the tops).
     I put Reel 3D adhesive securing tabs on the chips at the part that is
cut out on the RBT. It's helpful to hold the "mount sandwich" where you are
putting the tab down on the chip against a solid surface (like the edge of
the light table) so as not push the chip off the sprocket posts.
     Since the chips are at the edge of the cardboard mount, the half of the
tabs not on the chips won't stick to the mount.
     Next, square the top of the RBT up with the fold and the sides of the
Spicer mount; thumb and forefinger still holding the two together, pinch the
tabs at the bottom of the chips onto the cardboard mount, carefully slip the
top of the chips off the sprocket posts and slip the trimmed RBT out.
     I make a final check that the tabs are firmly pinched and inspect the
top of the chips and the mount fold for parallel. Ready to fold over and
check in the viewer... haven't had to redo one yet!
     I don't tape(tab) with this method until I'm confident the alignment is
OK.

     With practice, this doesn't seem to take *too* much more time and if it
seems a little more time consuming, I think about all the film the savings
will buy.
