I had to do this with my Tex Mex pickups. On a 9.5" radius I could not get a good string-to-string balance with the default stagger. With the pickups straight across, the high E suffered badly reduced output compared to the other strings. When raised up on the high E side enough to compensate, the G was ridiculously loud. I use EB Hybrid strings - 9-46. I probably could have played around with a custom stagger pattern, but I just flattened all the poles and raised the high E side slightly. I really like these pickups now, but they were harder to dial in than my other Strat sets. I have three other Strats with SD Alnico II Pros (with a custom wound Vineham bridge pickup), a custom A2/A5 Bootstrap set, and a Bootstrap Oatmeal Stout set. Unlike with the Tex Mex set, I can't get these other sets to sound bad at any reasonable height. There is some wax in there on the Tex Mex set for sure, but they will start to move with a little effort. With the plastic bobbins, it's totally safe to push the poles up and down.
