What is the difference between tiers? For example me and a buddy play each other a lot and we were the same tier for a while. Now I've moved up to the next tier and I've my play has declined substantially. I am tour pro he is pro
I think the only difference between pro and tour pro is the green speed. I am pretty sure both pro and tour pro play off of the same tees,
Also, by default, the higher tier's game conditions will apply in mutual games. That includes the higher green speed (beware!) and, possibly, higher winds.
