[What golf ball do you play?]

I always try to play a ProV1, what a grew up with, what I'm used to. 

 

That being said, I don't mind the Amazon deals on the Z-Star or the '16 Tour Preferred. Basically any soft tour ball I'm happy. 

[Does anyone walk anymore?]

Walk all day long. People complain about golf being too expensive. A walk on a muni shouldnt be more than $60 and on private courses it's "free" (included in the dues). Always walk.
