well find out why it feels wierd. its probably the head tube angle, so find out what headtube angle suits you best in the park by testin other peoples decks. then go buy one. the other things it could be are weight and length but its probably hta.
in my experience you can get used to most decks by just riding them, then you dont have to faff about with 2 decks. i went from a RUP to an MGP to a VertX with little problem
