Make it handle

[robnolimit]

The longer spring will 'almost' always ride better. So, if you have a choice, go with the 2" block first, then drop with springs.

OK, they are new but the Wilwood drop spindle big disk kit spindle may be worth looking at. In your case, with a 2/4 drop, the un-sprung weight savings on the spindle/brake assembly would help the ride/handling. I'm not so sure that this spindle is great for everybody, because for the guys going farther, away from the OE geometry, there are better options. But, for 'mild' builds this is a worth while choice.
