Replying to ON3P Jeffery Mounting Point

Sorry to start another one of the mounting point threads. I'm downsizing my boots and don't feel like remounting (cause I have pivots that won't adjust much). So I'. basically liquidating my quiver and replacing it all (for now) with some Jeff 108s in 191. Prolly like 15% park on these but I'll be spinning and throwing tricks all over the mountain. A lot of people just say go rec but I some kartels that I had between center and req that felt pretty solid. I've also heard a lot of the ON3P team guys mount -2 from center. Is this true?
