Bert. I agree, it could be said ppl worry about smooth PE too much, smooth PE can be guided out, yes,its random spikes that are a worry. I didnt bother with PEC after struggling trying to get rid of it, to no bad effect.
mmm, backlash, well, its not a problem with out of balance RA, for DEC, yes, but I cant say I had a problem with it with a standard set up with the worms tweaked a bit. Of course its better with no backlash, im just wondering how far its worth going to eliminate it, (given you have fixed that already).
