What has been people's experience with microclover/grass mix lawns? In theory they sound incredible, but I'm afraid that the clover will be so hearty that it will take over the entire lawn.

Here's an example: http://protimelawnseed.com/collections/sports/products/rough-ready-eco-turf

I have a large dog, three young kids, and a 4,000 sq ft backyard. I want something that can deal with the punishment, keeps the weeds away, and is easily maintained. It doesn't have to look as nice as the front yard.
