For me, they also aren't too heavy or light, so hitting with them feels fine
I also liked using the can of Slazenger balls I bought. Only problem I had with them is the logo of the ball wears off, which kind of bothers me at times
My current ball of choice is Pro Penn Marathon Regular Duty on the clay. They are very bright which is nice at night and not too heavy or furry.
