I was given a 2-ball sleeve of the new Mizuno RB Max balls this week. Went out and played 9 holes with them and I’m very impressed. It feels fast and comes off woods & hybrids with a nice crack! They are saying that it’s an 80 compression - but to me it was only mildly firm. I’ve been used to playing a SuperSoft - so, it was firmer than that. Distance was good, nothing negative at all. Felt like I got more carry. Love the way it feels putting! Plus... it seems to be very durable. I went back and purchased a dozen!
