Same with dips - I could do them without back pain (at least not much). So I did them in place of the press until my back got better.
I liked dips so much that I've added them to my weekly training regimen as a press accessory. I've been progressing them by doing the following:
Session 1
(BW) - 3 sets of 8
Session 2
(BW) - 3 sets of 9
Session 3
(BW) - 3 sets of 10
Repeat the above, but add 5lb to body weight.
