I only mentioned a size up may have the pop I was looking for because the 150 for me isn't really a jump size and the 153 is likely to be a little stiffer and therefore a little poppier. If you weigh more than I you probably want to go a size up from the 153. That being said its possible you'll lose the fun playfullness by upsizing. The Ply may just not be able to blend poppiness and play like say an Arbor Blacklist, Salomon Drift rocker, and likely the Signal Park Flat.
That thing I do to escape the world and have fun with my friend
