Is speed an agency requirement for you? It seems to me that being able to do it while holding position and keeping an eye on your buddy is more important. (Slow is smooth--smooth is fast.) Agree with pointing your elbows forward, not out. Keep you head up too.
Nope, keep your head down (horizontal) looking towards the floor. Your neck must be straight, looking up or down causes problems. You want to maintain a relaxed posture!!!
I agree that smooth is slow, but my instructor demand 30 seconds start to finish. I think IANTD requires 40 for trimix.
