what soil/mix are you using?

I have read so much about peat based soils. Their advantages and disadvantages.
What are some alternatives that work well and don't take a whole lot more upkeep.
I liked the COCO i used, but was always told i should be feeding them nutrients daily. Every other day was too much for me.What i really liked was the ability for the roots to really expand in the coco.
I also added some coco to FFOF (with 20-30% perlite) and had pretty nice success, but i was nervous because i wasn't sure what to PH it at. Still don't?
I am getting close to filling some 50 Gallon bags and wonder what ya'll think?
