I've got 38,000 on my Bridgestone Dueler ATs and have not had any need to rebalance them. I'm also a long time Michelin tire user and was cautious (and concerned) about going non Michelin.

I've been very pleased with them... outstanding performance with regard to not hydroplaning in standing water..

The only caution (and in my experience, this is true with any wide tread tire with large, deep tread blocks that have tread pattern cuts running across the tire from side to side) is rotate them say every 5-7k miles from front to rear and, especially make sure your front end alignment is perfect (particularly make sure it has only the minimally required amount of toe-in) to avoid outer edge, leading/trailing tread block wear at the front.

I measure my tread depth across the tire every time I change the oil and, if there's any significant difference in depth, it's time to rotate them so the wear evens out on the rear.
