Aluminium vs. Steel for Polo Frames

i really do think weight makes a difference.

if you are on steel at the same ratio as someone on an alu frame, you will have to work much harder to keep up in games. you will feel this when playing 20, 15 minute games over a weekend.
Horses for courses. I can't say that weight has even been an issue and if it were it's surely easy enough to gear down.
