I think that might be the best way to go, Duffy, although I would have thought (my preference) the rail would have been in the bridge position. The obvious advantage of this is to put the beefier, thicker, rail in what for many, is the most unusable pickup position on a Strat. Additionally, it's a way to get more of a humbucking tone without having to route a S/S/S body for a full size humbucker (as is also true for the other two positions as well).

If one can afford to do so, the ideal situation is to have several Strats, all set up in different configurations. I had a set of Joe Barden S pickups in a Strat once. They sounded great, but not great like single coils should. They had a character all their own. I regret selling them instead of saving them for another Strat set up just for that tone.
