My friend and I have been practicing the regular side stroke for a couple months now, we shaved our times down to barely under ten minutes but have failed to get any faster for some time. I decided to switch to the Combat Side Stroke to see if it was any faster, it definitely will be an improvement as soon as I get used to the new style. However, I was wondering if during the PST if you had to use the same side for the whole 500 yards, or if you would be able to switch?
