I don't do them often, but I occasionally do overhead pin presses, which incidentally is an elitefts.com listed M.E. exercise. I have pressed around 350 over my head from a dead stop at my hairline (take that B-fold). I think it is an exceptional M.E. exercise, though not all agree.
I hate floor presses. They hurt my shoulder. Some people have used floor presses and put 50 lbs on thier bench in 8 weeks, though, so you have to see what works for you.
I have a very unorthodox exercise that I just love, it is my "magic" exercise. Shirt/board presses. You have never read an article about them, but I have put over 50 lbs on my bench with them in the last 3 or 4 months.
If you are lucky enough to find something that works for you, milk it to death. I have taken some shit for some of the things I do. I bet Noah was ragged for building a boat in the desert too.
Just be real careful at the bottom of the press if going behind the head. I personally only do them off pins. I feel it is safer.
