Replying to A few last minute questions

First up let me explain. Im sure you guys have heard from previous threads I am buying fujatives and either look P12 jibs or Look P10 Lifters.

I need to know if it s really worth it to buy the P12 for the extra money or if the P10 will have a high enough din setting for me. I am about 160#'s and and just getting into skiing. I the din setting 10 going to be high enough or should i go for 12?

Sorry for the noobish questions guys but i need to know this stuff.
