Personally I think the 3/8x10 joint is a soft hitting joint. The OB itself is also soft, when pair together, it's a real mushy hit in my opinion.
It has a lot to do with the everest tip that is stock on an OB. At the end of the day, it's all personal preference.
That being said I never liked the deadish hit of an OB1, and when I had an OB2 added to my carolina, it was a bit of a hassle to adjust. (I got it on a trade, and I wanted to try 11.75 LD).
I switched the tip with a Tiger Hard layered tip and that did the justice for me. It ends up hitting like a good medium to medium hard tip.
So in short, if you like a super soft hit, that is the combo for you. I would suggest that if you're a fine cutting/super english player.
