Replying to Yes another binding thread, FKS 115mm on a 102 mm ski...

Hi guys, hope you can help me out.
I just got new K2 Shreditor 102's as an all mountain ski that I will also be taking in the park occasionaly and am having trouble deciding which binding to put on.
I have 2 options:
I have new marker griffons with 110mm brakes that will fit fine and have a jig for. Replacing brakes is also no problem at all.

2nd option is to put on some brand new rossi FKS 140 with the 115mm xxl brakes on.
I can get these for free and then sell my griffons, which sounds perfect as everyone thinks fks are much better and they are free.
I am however worried that the 115mm brakes will be a bit too wide, especially when landing switch on jumps. Do you think I can bend them in a little and not have troubles? I allready placed the heelpiece over the ski and it sort of looked allright, but I'm still a little worried as I dont feel like blowing out my brakes on an FKS...

I will be mounting them tonight, so I need to make a quick decision. I also posted this in the general what binding thread, but didn't get a reply!
I appreciate your help! Thanks
