Replying to Binder question/help

Ok, heres the deal.  I am 5'11 about 190 lbs and I have been skiing park on rossi axial 14s(pivot)  for the past 4 years.  They are all busted up now, and places are refusing to mount them for me, which is a sign that I need new binders.  the problem is that my skis have also broken, and I opted for new skis before the new binders.  Now I have literally NO money, but I do have a pair of axial 10 (pivots) on my brothers old skis that are in prime condition. 

I am a very aggressive skier, and had no problems with the 14s, but they were probobly too much.  12s seem like they would work as well.

on the 14s I kept the din at about 10, and had no problems whatsoever.

My question is aimed only at people that know what they are talking about:

Do you guys think the 10s would work, keeping the din at about 9?  Are the springs just too weak for me?  I put the dins up and snapped in, and pressed around the carpet a bit and had no problems, but I'm not sure about the legitmacy of this.
