I personally shim mine with almost zero backlash. In fact I do shim them with zero backlash from the beginning and when they wear in, I re-shim them back to almost zero. You have to keep them really tight or they will blow out.
When shimming them like this, you will get that notchy feel at least in one spot. This is fine, and will wear in with time. As long as it doesn't lock up the notchy spot won't cause any problems. I also recommend using a good grease like Mobil 1 red bearing grease on the R&P.
When you drop the whole mess in the case with shims and all, do you have any side to side play when trying to move the outdrives to the left or the right.
Also, I think having the driveshaft as tight as possible to the pinion makes a big difference. The pinion should not move in or out. What are your thoughts on that?
I read somewhere there are aluminum cups (the half moon parts). Have you heard of these?
