If you go with an a2 for the bridge, you might want to change to a .02 cap, An a2 will be darkerA3 neck, A2 bridge? I do like the mids they should bring.
I'll take a stab, though other have more knowledge, & can explain better.
A5, being almost the strongest alnico magnet, tends to pronounce the lows & highs (mostly lows from my exp) with a mid scoop, while A3 being probably the weakest,, seems to amplify the character of the wind (not tending to over amplify bass/treble) being more neutral.
Bridge, A5, tends toward brighter/thinner (string vibration, or lack thereof being the reason), but boosts output. A2, while not as strong, tends to be more even, & will "thicken" the tone, (I like A2 for bridge, & a4/uoa5 for neck)
Old rule of thumb says, set your amp for the best neck tone, then dial in the bridge with the guitar controls, the bridge will be too bright, but then dial back the vol a tad & tone a touch at a time, till you get back to the warmth that you like.I could live with the A5 in the bridge, and I do like my setting on the warm side, but when I set up for the best bridge tone, the neck tone is too bassy. That's the dilemma I am having.

And I quote: -
"A2 long / Scooped mids, chimey highs, warm sweet tones, loose feel.
A2 short / Scooped mids, spankier tone than long A2.
A3 long / Very weak, nice clarity for use in P-90's but very low output for P.A.F.'s.
A4 long / Balanced mids, treble and low end, drier toned than A2.
A5 long oriented / mid dominant, focused tone, jazzy cleans.
A5 short oriented / mid dominant tone, fatter toned than long oriented A5.
A5 long unoriented (Illinois) / Great low end clarity with good mids.
A5 long unoriented (Indiana) / Less low end clarity more treble snarl, good mids."
