Haha, I left myself a note and then forgot. I still use it as my primary blade, which I didn't expect. It was an experiment that has worked out well.
The handle is thinner than I like but I added a grip. Mine is 91g but feels lighter. Despite the smaller handle it isn't too head-heavy. The two sides play clearly different. The spruce + inner PLC side is livelier than the various limba inner blades I've tried but it still has more dwell and a softer touch than an outer carbon blade. It's kind of a nice in-between actually. I've put Glayzer on this and a Yinhe Pro 05 and while the rubber feels OK but kinda dead on the Pro 05 it really comes alive on the Pro 11s. The koto + outer ALC side feels just like other koto outer blades I've owned -- backhand loops, drives, and counters are very stable.
If I had one complaint (other than the handle), it would be that the FH side doesn't feel quite as solid as I'd like on harder hits, e.g. smashes. I think the core could be ~0.1-0.2mm thicker, which would solve the handle size problem as well, though it might cost some flex.
