Hey Kelly,
Those are nice amps, I still use my 2203 as my main amp.
Evo2 is definitely a good pick for everything you mentioned, and it would definitely work with PT middle and Chopper in the neck. I'd still reccommend a Satch Track in the neck, as it's pretty versatile, can sound like a true humbucker but sounds beautifully split as well.
JB is a bit different animal. It has some similarities with an Evo2, but it's fundemental tone is different. Whereas Evo2 is tight and controlled with heavier gain, JB tends to flab out, where Evo2 cuts with treble detail and presence, JB cuts with a high midrange spike. Both of pickups are very versatile, and can do pretty much any music genre out there.
It does definitely work well on superstrats, and it works even better on a 250kohm or 300kohm pot then a regular 500kohm. If you go this route, pick a medium output singles, because otherwise the JB will completely overpower them, the JB is pretty loud pickup.
The only issue I found is that JB sounds dead in an thin agathis guitars. I have no clue which Washburn series yours are, but one of my Washburn Idols were agathis and could never get JB to sound well in it. The Custom and Custom Custom worked wonders in that one - sadly I don't remember trying Evo2, but DiMarzios tend to be less coloured by guitar wood type then contemporary Duncans.
Crunch Lab is excellent for what it does, if thick leads and groovy rhythms is your thing, CL does it excellent, but by the music types you're playing, I'd think it would be an overkill.
Illuminators may seem like a monster output pickups, but they're not, I found them pretty versatile, they're just loud and bold pickups. They cut through even the densest mix, they sound pretty balanced. Between it and Evo2, however, Evo2 is more versatile and smoother, and a bit more expressive.
PAF Master and A67, are low output set. They're excellent for blues, classic rock and rock and hard rock, but they might lack a bit for Vai, Satch and more modern sounds. Any PAF can sound modern and tough, but it usually requires a modern high gain amp, with an 800, those things rock all day - but might be lacking for more then that.
HTH,
Cory
