That won't be super heavy. I've used my Mojo 90's with p12's in the park and it's not bad, and those weigh a couple pounds more than your setup will. Lighter skis aren't as good for skiing around the mountain, either.
Karmas are not heavy! They feel pretty light to me. If the karma is to heavy for you maybe try skiboarding. Actually, IMO karmas and 614s would be one of the sickest park/all mtn. setups you could ride.
