I used a mix of sedge peat (cheap "black stuff in a bag", as I call it), pine bark, and thermal compost in some 24" pots with no problems.
Most of what I have experienced is covered here regarding nitrogen availability, fungus gnats, and weed seeds. I have used 3+ year old leaf compost for potting up seedlings in 2.5" pots with great results, only to be followed up with 100% failure when I used some 1 year old leaf compost that looked like peat moss.
The 128 cell trays I use for seeds are such a low volume, it is worth it to use a peat/coir-perlite mix. Even with this mix a few fungus gnats usually appear. Amazing little things.
