You could mix, but I don't see an advantage really.. Either one is fine. Roots will probably drain better. The only complaint I have about roots is that it will definitely come with a free serving of bugs. You'll have gnats within 20 minutes eating the shit out of your babies.
To counter this I hit the roots with a dose of Knockdown Garden Spray and I add 1-2 inches of sand from Home Depot. This takes care of it. Without the sand you are hosed.
This is just a hypothesis, but maybe roots keeps a more stable PH over time. I felt that when i used Ocean Forest that maybe some of the organics were breaking down and turning my grow acidic.. just a thought.
