I don't think you can entirely blame the NR Shifting problems on the rear derailleur. The Shifters themselves have to take some of the credit.
The best solution for NR and SR shifting is to switch your shifters to Simplex SLJ's. I know it's not cool to "mix and match" but sometimes you just have to.
