Replying to Where to mount Line SFB

Hey guys, so I recently impulse bought a pair of sfb's.... the price was to good not to. I am mainly an east coast skier but I do usually head out west once or twice a year. I am 6'3 200 pounds and bought the 189 version of the skis I also ride 50% all mountain 50 % park. I am torn right now whether to mount these skis at the recommend line or whether to centre mount them. Ive have always had centre mounted skis in the past and love surfing and jibbing around the mountain. Any suggestion would be super helpful. Cheers!
