Replying to Im 6 foot 4 inches, and i want a 155-158cm park board!

hey guys ive been ridin for 2 years with my 165 board, yes ive been riding that board in the park...   I can throw 3's and all grabs, and most rails.  I want to get a new board like a 155 or a 158 because i want to be able to do spins better and be more manuverable with jibs and stuff.  im 6 4 Is a board this size gonna be just to small?  i put one up to me and is about 2 inches below my coller bone haha.
