On the contours, what I like is the one in the back for your ribs, but on the front I like the nice square edge to rest my forearm on - I can play better on a guitar like that. But then, there's at least a half-dozen things I don't like about Stratocasters, and some people have managed to muddle through on them regardless of my insights. :icon_scratch:
Regarding pickups, there are a lot of people making P90-sounding pickups that fit in standard humbucking routes. One good reason to stick with the regular humbucking and strat-sized routing is it's easier to change pickups, if you're like most people you always hope to find talent-in-a-box!

DiMarzio, Rio Grande, Lindy Fralin, Gibson, GFS, Bareknuckle... surely there'll be a good opera pickup in all that. :icon_thumright:
