well first off that salesman is either a douche for trying to sell a inferior product so he can make better commission or hes an dumbass and im leaning towards the latter knowing the intelligence of most salesmen in snowboard stores. The k2 would be a great board for you however if you really wanted to get a different park board for less than 450 you could go with the Capita Stairmaster, Capita Mid Life Lost ( both available in wide), Burton Blunt Wide, Forum Destroyer Wide, Nitro t1 Wide, Nitro Team Art Attack Wide, Ride Dose. Thoes are a pretty good spectrum of good park boards that range from low 300s to 450. All are available in wide. I would personally recommend the Nitro t1 or Capita Stairmaster. Up to you, and good luck with your purchase.
