I have used Team Issue and GST's in the past. GST has always been my favorite, kids didn't mind the Team Issue Ball. One time we went with Wilson and they were terrible (leaked air, rock hard, etc). Just my experiences...
Speaking of "mudding" anybody have a particular brand and/or process they swear by?
Lena Blackburne Baseball Rubbing Mud.
Multiple ball brushes
Football oil
Football tack
Heat gun optional
Process for a new ball:
Brush Ball
Shaving Cream Ball - let it stil for an hour or two
Brush ball again
Mud ball - use a thin layer of mud cover everything except laces. - let is sit 24 hrs.
Brush ball again
Oil Ball - Wilson has an oil Big Game also has an oil GridIron Football Prep has an oil
Let ball sit 1-2 hrs.
Brush ball
Tack ball - I like a bar of wax that Wilson has bush in the wax and then you can hit it with a heat gun off and on while brushing it.
Then for an older ball oil and wax before the season. You could wax and brush game ball each week.
I'm no expert at this but I found our treated balls lasted longer and had a better feel. I've thought about starting a side hustle.
