I'd bite the bullet.
You paid more for that hub than lots of people pay for their whole bicycle. That deserves a proper, no compromise, wheelbuild job. If, every time you look at the bike the wheelbuild causes you to worry or wonder or just affects your serenity, it wouldn't be worth it to me.
No mechanic likes come backs. Second come backs are even worse. But dammit, it's their fault. You paid for a good job and you got a build that has you wondering if it's OK.
