Aluminium vs. Steel for Polo Frames

alu is lighter, which i believe makes a huge difference. most peoples polo bike are ridiculously heavy.

In polo, it's acceleration from a standing start that is important. 2 or 3 things will affect this: length of cranks - shorter cranks = less leverage; rotating weight, ie wheels, heavier wheels will accelerate slower; stiffness of b/b, rear triangle area, ie when you push down on the pedals, the less sideways deflection of the rear triangle area. I reckon that weight of frame has little impact on any of these factors, but ally is generally stiffer so will deflect less (all other factors being equal). Personally, I prefer steel because it is more resilient. The ideal would be a ti frame, very durable, light and can be made stiff. Carbon is, of course, a poor choice.
