One major misconception about Vekoma is that people in the US have mostly experienced so far pre bankrupcy Vekoma era. In 2001, Vekoma went bankrupt and out of the reorganisation, things changed a lot. Everest and Grizzly mountain runaway mine cars (hkdl) along with Freedom Flyer at Fun Spot are nice representations of that era. Smooth, well manufactured rides at a nice price. Alas, Six Flags abandoned large 15-20 millions investments from 2012 to 2019 and Cedar Fair been spoiling the same parks with massive rides from B&M with some GCI (Great Coasters International) wooden coasters sprinkled in there until 2018. Did not leave much space for Vekoma new products there.You raise a very interesting point I've thought about before.
I think with Vekoma you have a company where if you are willing to spend the money they will produce a high quality, reliable coaster that is above all highly customised to your requirements. B&M are know for being very inflexible and Intamin unreliable (and a slightly dubious safety record at times).
Vekoma have also been very willing to step in and help with other coasters Disney have bought from other manufactures, I believe they have replaced track and systems on both California Screamin' and the Indiana Jones coaster at Paris. It wouldn't surprise me if much of the remedial work done to Primeval Whirl was done by Vekoma either.
The problem is most parks go to Vekoma for cheap/cloned coasters.
Six Flags hooked their horses to the RMC wagon and it diverted a lot of ressources that could have gone to other routes . Cedar Fair tried that route last year to no success.
What changed at Vekoma? They upgraded fabrication yet again and hired a genius as a layout designer. Brilliant creations such as the Firestorm, Shockwave and Lech Coaster are from him. Intamin also hired a new guy and his "family launched coaster" that I rode last week in Shanghai was brilliant Steel Dolphin
American parks are behind the curve now for new coasters amazingly and you need to go to Europe or Asia to experiment the innovative rides.
Back to Tron at SDL, rode it last week and its still perfectly smooth. I had a ride in the TAV (Transfer accesdible vehicle, the standard seating car) and its a very different experience. In case you're wondering, out of 8 trains, two have the TAV in Shanghai. Tron in Shanghai runs 6 trains at a time.
