I own the BMX88 and skied the Brahma earlier this week. Very different. Agreed that the Brahma is a much more powerful ski that held much better at speed, but I don't think it is more versatile for everyone (e.g. me). On big east coast bumps the Brahma was really throwing me around, and I wouldn't want it in trees, either.. For someone like me, who's shorter and lighter, I prefer the Bushwacker or BMX88.
I had the same feelings on the Brahma. Another skier was describing it to me: it likes a "pivot" at the top of the turn, not a primary tipping initiation. The way I ski, more of an active down-unweight, relax that outside foot, shorten that old outside leg, and tip at parallel edge angles, and not a lot of weight to bend the ski, I found it to be more work and no more rewarding than softer skis. The ski doesn't like to be loaded at the tip, it is pretty vague if you really crank your feet back and then extend. I felt the exact same thing on the Bonafide; it has something to do with that tip rocker and stiff flex. Most people I see skiing on the Bonafide also throw in that pivot at the top of the turn, now that I think about it. My Kabookie likes my preferred release move much more, as do my 8.5ti's. I can really relax that strong leg, pull the feet back, and begin to extend without the skis pushing me back upon the extension on the back side of the virtual bump. Interestingly enough, the Soul Rider and FX94 I skied at the last demo was probably the most money in that type of turn. It has something to do with tip flex and marriage of rocker. The Soul Rider, being much softer, allowed me to get edge engagement at the top of the turn, really load up that outside ski, even though it has quite a bit of rocker at the tip. The difference I think is perhaps the more round profile of the rocker and softer flex allows the top edge of the ski to engage early, with softer flex that helps for me to bend it.
There is a ton of technique issues involved in ski purchase. The more I talk with people and see how they skis, and what skis they like and why, it seems that skiing style is as important as height/weight/skiing speed.
I do think the Brahma is going to be a good ski for a lot of people, plenty will find it solid, stable, and reliable for how they ski. Like all information on here, YMMV.
