I think it would be interesting question to ask people that post replies:"What pu do you use?" One thing that seems to me that most of people recommend pu THEY USE for everything..it's like..guy asks for country sound pu..and people respond:Tone Zone+Air Norton!!!..lol ;P
Anyway as far as your question goes..one thing to be aware of..you said:"I would like the hottest possible pickups that are extremely articulate and clear, and have great harmonics." Hot and great harmonics could go together,but "hottest possible"+"extremely articulate and clear" combo is like asking to have a drink that is at the same time warm and sweet like a warm cacao and refreshing and cold like icy clear water->?

You can have some pu that are pretty hot and acceptably articulate and clean..but "extremely articulate and clear"+"extremely hot"..NO. With stuff like X2N fogret about "extremely articulate and clear" sound

Unfortunately if you don't have money for few guitars you must see what is most important for you and make some compromise that you can live with. I did that too in my guitar(basswood RG450),not perfect for everything but I am happy with it,and people say it sounds great...Air
Zone bridge(versatile,clean,articulate, great hard rock sound,good metal and blues sound),Virtual Vintage 2.1 middle(nice strat sound) and Breed neck(smooth distorted Vai sound,not so good for ryhtm on neck though,bit bassy). For your interest in music(Symphony X?) and some versatility also try Tone Zone+Air Norton(DT Image and Words),
Breed bridge and neck(Vai),Norton+AN(kinda Van Halen,bit more power though)..avoid Evolutions and X2N if you want articulate and clean..evolutions(especially in basswood)..are crazy pu that need very very good equipment(think Vai equipement) and very very good fingers(think Vai fingers) to keep it controlable and not just a lot of noise..if you hear a player that sounds crazy with some pu..think more how expensive equipement he has to tame all the noise from so hot pu.
More output,more hot->less articulate,less clean..goes worse and worse when going into extremes(X2N stuff)..better choose little less hot pu..and you'll still have very hot sound with lot less problems with uncontrolable noise..and much more articulate and clean..good luck
