I just ordered a trs and our styles seem right on par. I ordered the 154 coming from a 159 burton supermodel. I feel like the reverse camber profile will be far more effective and efficient on a shorter board. I believe their rule if thumb is you can subtract 3 cm no problem. I generally prefer a bigger board as I'm big into freestyle carving, loads of switch also. I'm 5'9 150.
If you are looking to do big rotations, trees and butters( 360+) you'll prob benefit from the shorter end. If your more into beast carve mode and free ride, I'd go bigger.
Note, 154 is middle ground for you. So it's still not that short.
