I prefer to dwell on the success stories, but if you want to hear about the stuff that didn't work out . . here goes. . . when I removed my average sounding, lifeless Fender pickups I put in a set of MEC's (from Warwick via the Bass Centre). IMO they were OK but nothing special. I then put in some SD's (can remember which ones). While it was getting better, the sound wasn't quite what I wanted, so I went over to Chandlers who put in a Bartolini P bass pickup. . . . and that was it! A great full, fat tone. Tons of low mid punch.
