This is my first ever review. As a background, I started playing TT over a year ago to see if I can be a proficient in a new sport in my early-30s. I play a bunch of other sports since I was a kid.
I bought a Korbel Japan when I was starting out based on reviews that say it's a do-it-all offensive blade. I found this to be true and it helped me a lot in learning the basics quickly. The slightly larger head size helps with the feel and control - it's also great for trying out new rubbers as it these would certainly fit most other blades after the Korbel.
It's hard but has more flex compared to, say, a Viscaria. Limba outers offer a bit more dwell too. I started out using this with Hurricane 3 Neo on FH and Acuda P2 on BH. I later changed to Hurricane 8 mid and Tenergy 05. I still have this setup and use it when I want a great workout with the longer FH strokes. Sometimes, I would use the T05 side for FH loop drills and I really enjoy it - less direct than harder 5+2 blades but more controlled and with a nice arc. I find that with Korbel and T05, I can take the ball much later.
The comments about the handle being too thin are quite true though, honestly, I only noticed this when I bought a Viscaria. Some grip tape on the thinnest part took care of it. I'm 6'1" and have fairly large hands.
All in all, a great blade for someone to learn the sport with and progress. I would advise people to try it and stick to it until you find that you absolutely need more power and are willing to sacrifice some control. I've seen a lot of guys at the club I play in use this at a very high level.
