Drop spindles vs. lowering springs

[atwot]

Which is better handling wise, drop spindles or springs? I have a mostly stock suspension. I'd like to go down about 2", and if there is no difference I'm apt to go with the springs. I've heard you can run into clearance problems when using drop spindles and aftermarket wheels (I have 18x8's now).

Also, can anyone recommend a good set of aftermarket A-arms? I'm thinking of going with global west ones, they are fairly inexpensive and I can reuse my existing hardware which is fairly new.
