hello guys.
I wanted to ask:
my club uses a lot of different types of training plastic balls every now and then. sometimes they tend to bring seam plastic training balls, some times seamless, some times the different brands causing the balls look and feel really different, for example- dhs 1 star and the butterfly new training balls- that are even feel different when you rub them!

sometimes there are even balls that look a bit bigger i say.

afriend told me that seam and seamless have major difference between them, in terms of speed and rotation

so, is there anyone here who can make it all clear for me about all the balls and the slight or major difference?

thanks a lot, aprreciate !
