Replying to where do you set your bindings?

Ive met acouple of people who have had there bindings set right in the middle of there skis so they have an equal amount of ski poking out from the toe and the heel.
They claim that it gives you much better stability riding switch is there any truth in this?????
Plus if you gain stability riding switch do you lose a bit goings forwards.
p.s. if anyone wants to check out some of my photos ive just uploaded my first ever batch (how exciting :) )
