Hi everyone, can someone direct me to the right direction in buying a ball to play/learn altinha in the US? A great friend of mine is taking me to Brazil soon and I want to get better at this secretly to surprise him. We already play college ball together so I have experience playing ball but I know this is WAY harder which is why I want to be better. I did see some on amazon but read some reviews about the ball not being “soft bilt “ does that even matter? And what the PSI should be ?
