I just wanted to add, that being forward of the line increases stability of the skier, if you will.
flat tails especially, but on any ski to a certain point will make you a better skier, you need to ski a bigger ski than you would normally but this is what the pros do as well.
The easiest way to try it out will work best if you have a small foot size 6-9 and find a rental binding with free adjustabilty, if it dials back to the line it wont work.
At this point take your bsl and start at 4cm ahead of the line, you will notice a huge difference 7cm is usualy ski center and is reserved for park skis etc.
at 4cm+ you will notice everything gets easier except speed and powder. to compensate you need length and rocker.(you don't actually NEED rocker, but it helps on the right days)
example: take a kid 5'9 180lbs old school he's on a 171-174.
Today, same kid, must be a good skiier mind you 189 HB +4cm
leaving me on 198 AK rockets +3 just so I can hang.
