not to mention, recommended is -2... not a very big difference from center... i got my eps mounted at rec. and i love it, switch riding is super easy... and as for forward riding, i dont think it would really make that much of a difference, i mean anyone whos ridin these skis knows that the most amazing thing about the ski is how balanced you can be while riding super deep pow, no need to lean back far at all, and those tips just keep fighting to stay on top for you... so i really dont think 2 cm is gonna change much at all..
