A couple things.....First, consulting the Gravity Group and throwing their new trains on Beast isn't the "smart thing" to do. In fact, thats probably the most assine thing to do. If its not broke, don't fix it. Second, since when does Vortex, Flight of Fear, and Son of Beast currently have trim brakes? Thats news to me.
Now for my two cents about The Beast. I consider Beast to be overated and nothing more than a really big Adventure Express up until one part. Having said that, the coaster itself is a massive achievement and the double helix is still one of the best moments on any coaster I've ridden and continues to be to this day. When it comes to the trims, they are there and they aren't going anywhere anytime soon so theres nothing anyone can do about it. All the moaning and groaning in the world won't help in getting the trim brakes removed from The Beast.
