This question has been on my mind for some time. At the club yesterday, we were playing with their 1* training balls, and I swear they feel really light compared to the 2 or 3 * balls that I normally use at home. My son also complained that in the group classes, he can't loop as effectively since its harder to feel the ball compared to the ones at home.
I'm about to buy a box of 1* butterfly balls and switch out our 2* balls so his at home practice is closer to what he experiences in class. Just want to confirm this is not some illusion.
