Replying to K2 pettitors

Hey guys searched the thread and Internet in general and wasn't finding much on this. Just picked up a set of '14 pettitor and wondering where to mount.

Before I bought I was thinking +4 after reading seth goes +5 wondered if I shold push them up there or somewhere else completely. Coming from racing and some more technical big mountain stuff and want to be able to press, butter, ski and land switch in these but also still charge big lines.

Read one review that said nasty hinge point at +5 on the 2013s so nervous about that a little. Any advice would be awsome and anybody riding the pettitors would love to hear your thoughts on performance overall. Thanks
