I love single coils as much as anyone on this forum (maybe more so), so its great to see you guys flying the single coil flag. They excel at cleans, kill on leads (especially in the neck position) and do a lot of low to medium gain rhythm stuff really well, too. But a Strat with stock pickups would not be my first choice for tight metal rhythm tones - humbuckers just do that that kind of thing better. A lot better.
If people were better informed, I bet a lot of them would rather avoid neck humbuckers for metal leads and cleans.
