The viewpoint I take is that Tim has probably tried all or at least most of the options in his workshop, as he has all the tools and parts there, and then deliberately settled on the final design of each pickup. After all, it is a balance of all the parts that makes the pickup what it is. If he felt a certain wire worked with this design, and the hex polepieces with the Aftermath, then it is probably because he tried the alternatives and felt they weren't as good. Why would I then, as amateur bedroom player, doubt that wisdom and experience, and start experimenting with different magnets and polepieces. I'm 99,9% certain that I will NOT suddenly find a pickup combination that the majority of guitar players will agree is superior to the original. That is what all those.... people... on the Seymour Duncan forum don't get. They think that by changing one particular part they will create the ultimate tone machine (Alnico 8 magnets are their favorite snake oil).
