If you get stuck in a descent roll out just a degree or two of bank. This should be just enough that you can correct your descent without pulling alot but, not so much that you can be accused of not doing a steep turn. Then once you're back on altitude go back to the AOB you're looking for. Likewise, if you're climbing a little you can overbank by a degree or two rather than pushing over too much. Of course this is not how you should plan on flying a steep turn, but a technique to correct for.... NOT STAYING AHEAD OF THE AIRCRAFT!
