hey guys ive been following this forum for a few months now (though im still very new) and this is my first post here. i have a jackson dinky with emg hz's in it and having grown out of playing metal/ getting tired of my tone, i decided to get new pickups. after some searching and an awesome deal i ended up with the p-rail set. with this i plan to get a set of triple shots and push/pulls for phase and series parallel. while geeking out on this forum i discovered thatthere is in fact such a thing as magnet swapping and have become very attracted to that idea. i have yet to install the pups so i wanted to know a few things about this process first. i get that mag swapping for most pickups is as easy as (carefully) unscrewing the bottom plate and (carefully) replacing the old one for the new.

1)however, is this process the same for p-rails?
2)are uoa5's the best choice?
3)what dimensions for the mag?
and 4) i'm totally new to this so can i do this or should i stop while im ahead?

thanks guys
