My friend had an SG bat, which was rock hard in sound and just sounded horrible. I didn't really tell him straight up my thoughts, as it was a present from his girlfriend when they were both in India. I just said, "It is really nice, a little hard pressed and will take a little time to play in, but nice!" If I had bought that bat, I would have sent it back, it sounded rock solid. Much harder pressed than the Kookaburra I bought off Asad, and more than double the price! The bat actually broke on its second use too, he hit a ball near the toe, and there was a split from edge to edge just under the splice. This has put me off SG, as that bat was a complete plank. To think it cost that much! It made my Laver sound soft!
I have tapped up an SS, and they are lovely. There are some CAs which are pressed rock hard, but others which are softer pressed. My friends TRD was really soft sounding. MSR say they press their bats soft, but I actually found that the bat made a really hard sound at start, but dented really easily. Just not pressed quite enough I guess!
I also saw a well used Flare today, and the sound off that was incredible. I wonder if it was a one off, or if a bat just sounds that good after a long period of use. Pressing is a really important, yet strange thing...
