First I'll say that if the most negative aspect of this debut is that B&M makes horribly unaccommodating trains, that's a win for BGW.
That said, we definitely shouldn't let B&M off the hook here. Dollywood's Vekoma family invert, Dragonflier—a ride people seem to agree is more intense than Wolf's Revenge—has a height requirement that is three inches SHORTER than Wolf's Revenge's (39" vs 42"), has a max rider height that's four inches TALLER than Wolf's Revenge's (81" vs 77"), and runs trains that, at least in my experience, are very notably more accommodating and just generally more comfortable than Wolf's Revenge's.
BGW, undoubtedly, did a remarkable job with this project and it's definitely a huge win overall. B&M definitely wasn't the best manufacturer solution though if you ask me.
(Disclaimer: Yes, I'm clearly biased given my experience. I do think the comparison to Dragonflier is pretty damning though from a rider accomodations/comfort standpoint.)
