Re: Old/New Millennium of B&M
This that old B&M are supposed to be more forceful than newer ones are just an illusion in my view. In some cases it's the other way around. I think that the main difference between old an new in terms of force is computing power. The precision that you can calculate how the track should be built have increased a lot since the first B&M, and with better calculations you can get better force outputs.
Looking at data for some old an new B&M inverts, then the older ones are very inconsistent as their positive vertical force varies between every element (some spots may have 4.5 g's other spots 2 g's and the rest is somewhere in between), where as newer ones pulls more or less exactly 4 g's everywhere between elements.
It's like comparing the forces between a hand built and "tooled" NoLimits coaster track...
I'm leaning towards the older ones that B&M have made (Pyrenees <3 ), the newer ones are a bit too "perfect", they lack a bit of soul and character that the older have. But then again they are still massive fun to ride!!
