Cold weather polo balls
On the midwests 2009 thread a few people in cold climate cities have suggested using the "Hot weather--For use above 70 F" (21 C) red Franklin super high density balls whenver the temp is above 40 degrees (4 C).
Pros of the reds at lower temps: super fast, accurate shots.
Cons: welts/bruises from slapshots. They start cracking a lot below 3 or 4 degrees.
So, at what temperature makes sense to switch to orange. The oranges are rated to "above 32 F" (0 C), but they're definitely good well below that. At what temp do you winter polo players switch to the yellows?
