Larger Board Harder To "Turn In" ToeSide?

Hi all - just had a quick question regarding board size and binding placement (all the way out vs. one notch in). I have a few boards that I have accumulated through the years (138cm/139cm/144cm/145cm). I've noticed that the 144cm and 145cm boards are a bit harder to turn into the wake toe-side than the smaller 138cm/139cm boards (I'm 5'10", 170lbs). Is this a common occurrence with larger boards (ie require more effort to get on the proper TS edge to the wake)? Also, I've noticed its a little more difficult with my bindings all the way out to get a board to turn in TS....would one-notch in make this easier? Thanks guys.

It has to do with having more surface area and since your weight is the same, it takes more effort to sink the rail because there is more board riding on top of the water. Think about doing a perfect dive versus a belly flop, there is more water resistance on the belly flop because there is more surface area in contact with the water.

In regards to your stance, that is all personal. I prefer all the way out, but all the way out is different on a 138 vs a 145. Stance shouldn't effect edging other than a bad stance limiting your body's ability to get in its preferred athletic position.
