Replying to Binding DILEMMA

ok so hear is the deal.... I got new skis for this season and obviously need to put some binders on them, on my old skis i ran my older marker race bindings with a din of 12.

I run my skis at about 9.5 or 10_ i am 5 11 and 150 pounds

My problem is i thought i needed to up the din for my new bindings to a 14/16 but 12s are so much easier to find and cheaper...... Do you guys think i should up it or will i be ok staying with a 12??

thanks in advance, i gotta get these soon
