Replying to ASAP: SURFACE ONE LIFE 189 SWING WEIGHT

as you can tell from the very loud title i want to know about the swing weight on the 189 surface one life for me (6' 175lbs, dont want to sound like an asshole but im very fit) i would be usoing them for park, will i still be able to spin pretty fast? i dont really do more then like 2's on and if the rail is right a 4 off, will this become considerably harder with such a long ski? i know i should be on 179's but i was offered 189's for a good trade help would be great especially from someone in a similar place
