WHEN you drop DR doesn't matter as far as CDs alone are concerned except that you *generally* don't want to drop it during reck and CS. Thus, as long as you drop DR during SB and BB, doing so when it will have the lowest opportunity cost for that GCD and the highest gain is the goal. So you drop it when feather is high stacks, for a much larger DR hit. The cost is it replaces a BT inside reck, which doesn't matter that much all things considered.
I can't think of a reason to ever desync BB and Springs, though. I'd just macro them together. That being said I don't currently have my 2nd warrior to max engineering yet, so it is possible I am just not thinking of some reason you'd want them separate.
