Thanks Doug, Andy and Jeremy. The new and shorter chain didn't "suck" during its first ride, including dusty dirt, which is an improvement over the previous, longer chain which was starting to "suck" more frequently. As I said, there is no binding or grumbling when shifting to the big/big, and there is still slack left in the rd on this combination. Overall the system shifts very well with the new, shorter chain.
I suppose my question was moved by a dim, unreflective supposition that more slack means less tension, and that less tension means less friction and wear -- I am obviously in mind still back in the 1950s with those French racing derailleurs that allowed you to adjust rear derailleur spring tension manually. Multispeed bikes are so *complicated*, aren't they?
