Soft Cut Saw - Crack mitigation

It is pretty much impossible to make a slab completely crack free, the bigger it is the more likely it will crack.  Even loading it with steel won't prevent it.  Finding the real world balance, good fill, steel, good mud and some kind of joint seems to mitigate the bad ones.  At minimum I use tool joints but that isn't compatible with a power troweler.  With a slab this big (2100 sf) we opted for cut joints.
