DougK:Now I am thinking of going to dive in Cozumel and at least one dive company I have spoken with says they don't use decsent lines.
In regard to Cozumel, there are currents and you will be drift diving. The strength of the currents vary from site to site. My limited experiences have been that in Cozumel everyone rolls off the boat at the same time and the goal is to get down as quick as safely possible to avoid the current causing you to overshoot the dive site. Everyone approaches the decent a little different but if free falling (rather than finning down - head first) the best approach is to reduce drag as much as possible by let all air out of your BC and bending your knees and tucking your feet/fins up behind you....essentially going knees first to cut the water and reduce drag caused by your fins. If you have trouble equalizing your ears, then this quick, low drag approach may not work well for you. The same goes for head down, finning technique; some people find it more difficult to equalize in a head down position. You might tell the DM about your slow equalization and then he can direct the captain to select a drop site a little further up current from the target site on the bottom/depth level so that your slow decent will put the group where the DM wants to be when you get down.
