Replying to Rossignol S5 mount opinions

whats going on guys, just picked up a pair of the 09 rossi s5's and was wondering the mount opinions you guys think i should go w. i used to be completely park but w me getting a alittle older now im moving further to the pow so i went w these skis.  i ride park true center but want good balance and maneuverability in the powder, i know there is an adict  mount spot for truest  freestyle set position which i will set it on....unless someone tells me i can ride further up and get  about the same results as the prior.  thanks for your advice....
