Are you talking about with each stroke or on the turn? On the turn it is definitely hand over hand. With each stroke it is probably personal preference. Many world class breaststrokers extend them straight side by side. I do hand over hand as it feels more natural. The most important thing in the streamline is to REALLY shrug your shoulders foreward. Which ever hand position best facilitates that for you is the right one.
