Where should the bindings be positioned on the ski?

One local dry slope has the old fashioned skis, long, straight and bindings pretty much at the back of the ski. Where as another dry slope has modern carving skis with the bindings in the centre of the ski. What's all this about? i know i prefer the latter as it seems much easier to control.

Hmm, interesting one this. It does seem that Carvers, in particular, have centrally fixed bindings. That makes sense I guess, as the curve from tip to tail will be constant and the pressure point being central will require less effort.

But, but, but... my Screams have around 47cm of ski behind the heel binding, and about 70cm ahead of the front.

I would guess it has something to do with a compromise on "floatation" (or whatever the ski-related term is). When in softer stuff or blasting over crud you definitely want more area in front to keep the tips up. But given that Carvers are really aimed at piste work, they're made to be the absolute easiest to pressure into the carve?

I'm guessing really... we got any ski designers around?
