Replying to Center mounting for dorion pros

I know this is supposed to be in ski equipment, but I need a lot of answers before tomorrow. So, I just got some used 169 Dorion pro 1080's that were previously mounted at the recommended spot. I will use these for almost 100% park, mostly rails in the park and in my backyard too. I'm thinking about center mounting them. Is this a good dession, or should I just mount them at the recommended spot? And how far forward(cms) do I mount them from the line that marks the recommended spot to make it a true center mount? Thanks for the help.


And sorry, again, that it is taking up space in SG, I need some fast answers.
