Outside of other information, I've always used a default window  
scaling factor of 4, because that gives you the potential for a 1GB  
window and the granularity of the window is only 16 bytes.  If you  
don't negotiate window scaling up front, you are stuck with a 64K  
maximum window for the duration of the connection.  Besides, windows  
have always been updated on a coarse granularity, due to Silly Window  
Syndrome avoidance.
