The working portion of a dive is not necessarily the bottom part. I've done several dives where the deco portion is much more physically demanding than the bottom portion.
Example: Empress or Ireland -> no current on the wreck at depth but 2.5 to 3 knot current above 50 feet. Drift deco here would be a VERY bad idea as fog is common and the boat would never see your SMB. So you have to come up the line.
I did a dive with significant deco on a line in a 2+knot current. Once. It sucked BIG time. I was sure I was going to get bent about half way though the deco. The ladder to get back on board also ended up going inverted (so ladder should be angled this way / but ended up doing this \ ) once we stood on it, so I got to do 20 pullups on the way out for good measure! I was certain I was getting bent then. Dumped my gear on the deck, yelled for my deco bottle and laid down breathing O2 until it was gone. I think the only reason I ended up fine was I was on CCR and my buddy was on OC so I did about 15 minutes of extra deco at 20'. It also took us a good 30 minutes to pass up our gear due to the current, so that was all surface deco effectively, but I was working my butt off the whole time. It was stupid.
I recommend drifting.
