Get the 210 saddle.

If i was riding flat but rough streets with potholes, cobblestones, i would choose springs. Springs do make for a smoother ride.
Downside of springs- the Brooks with springs are quite a bit heavier than the Brooks with no springs. Also, some people have had very annoying problems with their saddle springs creaking and making noise.

I don't have springs on my Brooks, never felt a need for them. Some people love their springs.
