The helix at the end of the ride almost causes a "blackout" making that the most intense section of an invert I have been on. But the rest of the ride before that is force-less but still has an interesting layout. Not as intense as Nemesis.
I agree with nemesiscrazy here, I've been on Silver Bullet too and that last helix is insanely forceful, I had to go and sit down for 5 minutes after riding! It's a shame the rest of the ride was rather quite dull though.
Overall Nemesis wins for me, but there are definitely some parts of other B&M inverts that provide some real nice G's.
