Its been really bugging me I couldn't find this article again, but will post link to it here now in case is helpful again for anybody. Digesting this (particularly the flexure pics on pages 4 and 5) is what originally got me very interested last year in the potential for a well mounted small finder guiding setup.
All the feedback here consistent with this being a great way to go. Not suggesting we all need to race out and buy Borgs mind you.

Thanks again Brenden for liberating the finder I'd purchased for this, and Peter for showing I needed to get my act together.
