That isn't you both in wet and dry, right? If it is, something about your dry suit is changing your kick. The wetsuit diver inverts the ankles and approximates the bottoms of the fins well; the dry suit diver is not getting much ankle inversion at all, which is part of the reason for the short, choppy kick. A good frog kick gives you a very noticeable amount of thrust, which makes it quite comfortable and instinctive to put in a nice, long glide phase.
The guy in the dry suit is my buddy. We did fundamentals together. He got the tech card though. We don't know other GUE or technical divers in our region, so we are learning things in our own.
