This board has relatively few reviews written about it, probably due to its rarity and its somewhat unique position in the Bataleon lineup. Let me just say up front, this board was a total revelation for me. I LOVE THIS BOARD.
The Japan Edition is so, so light to carry yet stiff and responsive; it has TBT's benefits but the lower uplift and Twin shape keeps it mellow and closer to a 'regular' board in feel. It builds confidence just by standing on it, but doesn't overpower you. It carves like a dream, butters and presses effortlessly, and has such low swing weight it can be thrown around obstacles and moguls like it's made of air. It's a thing of beauty both to look at and to ride, and half the instructors on the slopes stopped to admire it :)
I was looking for a Bataleon after demoing an old Whatever and immediately feeling the benefits of TBT; I really like camber boards, but I don't like catching edge, I really like stiffer boards, but I don't like having to give 100% all day long. The Whatever was a nice, easy ride, so I resolved to try a few more boards out.
I tried the latest Whatever, Evil Twin and Goliath and found that besides the Evil Twin which I inexplicably didn't seem to get along with, the new Sidekicks were an amazing addition to the Bataleon recipe. The Whatever turned out to be slightly too soft for me, the Goliath was better but its shape was more specialised towards hard-charging, high-speed all-mountain.
Enter the Japan Edition, which although Bataleon don't advertise this very well, is the Whatever's shape with the board specs of the much more aggressive and high-tech Boss. Combined, you get something like a perfect hybrid of the Whatever and the Goliath, a mid-stiff board with park-like stability underfoot. With the possible exception of ultra-soft powder, I doubt there's anything this board cannot do.
If you want a quiver-killer that will actually excel at both park and piste and give powder a decent shot, this is the board.
Bataleon, if you are listening, PLEASE remake this board (especially with the lightweight core) for the 2019-2020 lineup! Don't change it (barring tech updates), just make it again. I cannot bear the idea that such a magnificent combination is 'consumable' and irreplaceable. You have utterly nailed it with this design, if you build it, they will ride!
