Really like the feel of my 19.5". It responds pretty well. Geometry is the key. The raw finish is a plus eventough I put a clear coat on it to prevent against rust.
Coming from my OG Sabbath, Im still adjusting to less weight and the balance that comes with that.
Finally a well rounded flatland frame from S&M that can be ridden around, and can let my OG Sabbath frame retire with honors.
