I've always found there to be two acceptable deep water techniques, the first is the one utilized by the foot dragger crowd, it is essentially keeping the ski tip pointed forwards, the tail shallow under the butt, and trying to keep the shoulders up over the front boot right away. This system seems to work, but I think is less tolerant if your drivers vary, I see this with some of my relatives who get pulled out the front if the driver is aggressive, and tend to sink under if the pull comes on slowly. This group tends to look down and take the wave over their heads during the pull.
The other group is the stand proud technique which is how I get up, which is a both feet in maneuver. I've found that if I flex my front knee too much my hands get pulled towards the binding, so I keep my front knee more extended, and the back more flexed. On pull I keep my head up and hold my hips in place so the pull very early on pops my head and shoulders clear and then I just wait for the boat to finish the work. To me this is the better way, but I have found that persons who break position mid-pull are less likely to succeed, and prefer to do more of a balled up position like the first.
