I was taught that my leading arm should stay outside my heel rail, as a general rule. Works great for going backside. But I see tons of vids and pics of surfers making frontside bottom turns with leading hand across to the inside/toe rail and trailing hand behind . . . and I've see the opposite, with great surfers turning frontside with the leading hand to the beach like I was taught . . .
What is the learning on this, I know I have to weight the back and turn my torso into the wave, look at the lip . . . Grelach is quited as saying get your body parallel to the stringer, but I don't want my arms in the middle . . .
