With the clutch on, shifting the chain is tight moving onto the big front chainring of 52 while the rear is in certain positions, plus, to remove the wheel the clutch needs to be turned off anyhow, so I just left it off. Next ride I'll test it again. The largest practical rear is 28 on my setup. I tried 30 but the chain when long enough to go big-big is too loose small-small. It took a long time to figure out to grind away some of the front derailleur cage and bend it down some to shift the front reliably. It's an IRD one specifically designed for the size chainrings installed. I like your idea of tightening the spring on the rear derailleur now that there is the old Shimano one to experiment with. Thanks for asking.
