I see reference above to the new MX98 having early rise. I have also heard the opposite. Can anyone provide absolute confirmation of whether the MX98 was tweaked to add early rise or if it is the exact same ski as before? Thanks!
To provide a contribution and not just ask a question, I have direct experience with the FX104 184 and BMX 108 188, not to the MX 98. I have also taken a few tuns on the 176 FX94.
Having skied multiple days on the FX104 and BMX108, albeit about a year apart, I think they have fairly different capabilities. To me, the FX 104 is an all around quiver killer that is probably the only ski I have ever owned that I would ski literally anywhere. Carving performance is top notch and on softer snow Kastle somehow made this ski feel shockingly "slarvable" for what it is (and despite the ample camber). The FX's most defining characteristic to me is its light weight. Having spent a lot of time on the Volkl Mantra and Katana, and even the Shiro which has no metal, the FX feels and skis noticeable lighter. The significant "pro" of this light weight set up is that it can be thrown around in tight spots very very easily and for a ski of its size and build (metal laminate) is very usable in bumps. I like a little early rise/rocker in the tail to slither through bumps which the FX doesn't have. However, by direct comparison to the Mantra which also has a flat tail, the FX is an easier ride in these conditions thanks to the lighter weight. My only negative comment about this ski is that it has a speed limit - also attributable to the lighter weight. A very high speed limit, but a speed limit nevertheless. For straighlines and general maching around I'd rather be on the heavier Mantra or Katana - the Katana of course being the top of the class when it comes to this type of skiing. However, picking the right ski is about trade offs and this is a relatively minor one for a ski that offers so much. It does make me curious about the MX98 . . .
As for the BMX 108, I put that ski in more of the big mountain charger ski category. I know die hards sing the praises of the old MX 108 that I never had the opportunity to ski, and perhaps the BMX 108 is "less" ski. Either way, I still felt very comfortable skiing fast and hard on this ski. It wants to make large turns consistent with its radius of 32, but will tolerable shorter turns. Its snow feel is trademark Kastle smoooth and it feels much less harsh than the Katana. Where it fell short for me, however, was maneuverability. I really missed the very slight rise in the tail the Katana (or Cochise) offer which makes them more manageable in tight spots.
