new park board for '05 question

i've been riding for 5 years in so cal with occational trips to mammoth/tahoe once a year. i'm 5'6" ~135lbs and currently ride a '02 152 ride fuel and want to get something with more flex/pop for the park, mostly jibs. i'm looking at a k2 "www"

now, my question is: should i go with a 147 or a 151?
i read on their website that they lengthened the effective edge and shortened the nose/tail to drop down a size. id like a shorter board (the 147), but will this be a drastic change from what i currently ride now?

I sell the World Wide Weapon, but haven't ever ridden one. I'd go with the 151 anyway. Added edge hold and width for off balance landings and various slides. Could use a sintered rather than extruded base though for the rails. Check out also the Ride Kink which is the same price range and offers a sintered base.

thanks for the input. i'll look into that.
juuuust when i thought i found a board, hahaha....back to square one i guess

how much of a difference does a sintered base vs. an extruded base make?

like, in terms of the ride feel and longevity. i've read that an extruded base will damage easier..but is there anything else?

Extruded is slower, damages easier, and absorbs less wax.
