Question on arm position in freestyle:

The first loss of a master is memory, the second...I forgot. I probably have already asked this question, but here goes: Does anyone bring their arm straight down and out after the grab? I am talking no sculling, no lateral movement, just bringing the arm straight parallel with the line maintaining the elbow high position. This would be to avoid crossing the midline with your forearm. Even though I breathe on the left, I still rotate fully to the right (a learned and trained and voluntary movement), but even so my right forearm tends to the middle, while my left arm has less pull and is erractic. When I learned the crawl it was from watching Tarzan movies, later when I was 16 and in a USA high school they taught the S shaped movement or the straight down and back. In those days the breathing was to one side. Last question: aside from timing both methods, what are your preferences on the long dolphin versus "less dolphin" emerging sooner method of starts and turns on a 50 meter short course freestyle race?
