I only received the KL-08 (Valentine's Day version) today and can't write a review yet.
I haven't played with it yet because I only got it today. The first thing I'm going to do is replace the hard leather tip with a Moori Medium. I don't like playing with hard leather. My only complaint is that you can't unscrew the weight screw. I had the KL-09 before and it worked no problem. It was also much deeper in the cue. With the KL-08, if you unscrew the bumper you can see the screw. 2-3 cm. It doesn't look like a weight screw either, despite it being hexagonal. You can't turn it a millimeter and it looks like it's one with the cue. I have to complain about that. And no screw fits behind it because otherwise the bumper won't go in anymore.
