I think it depends on how much you're holding. Consolidation may not make sense if you've got less than $10-15k, but over that it could make sense depending on the cost of the consolidation. But it also might be more trouble than it's worth. Say, if you have 1btc, what you save by consolidating may not be worth the hassle. It really depends on if you're trying to eek out as much value as possible, or if you're OK with just writing the expense off as just another inconsequential fee. This is all to say there's no single right answer, and it depends on your personal style and priorities.
