...
for a bookshelf, anyone have an opinion on which type of adjustable
shelf support to use?

The metal rail with clip is out of the question for this project.

I generally use the slotted metal rails that I put into a routed channel,
but if this is what you're say will not work, then how about a little more
information. A better description of the project would be helpful, as would
the reasons why various solutions would be inappropriate.
