I rode Montu last year and earlier this month, and I had great rides on it. The trims before the Batwing were never functioning, and the MCBR didn't trim off much speed at all. Montu is my favorite invert!
I wanted to mention Raging Bull @ SFGAm. There was never a time where it wasn't neutered, but it would be a much better ride if the third hill trims were never put on. Out of all of the B&M hypers that I have ridden, Raging Bull is easily the worst.
I also vote for The Beast and Son of Beast, easily two of the worst wooden coasters that I have ever ridden, all due to rough, boring rides.
