Yeah, I also agree. Take a look at the latest B&M inverts to be made, (Patriot etc) and look at the way that those coasters are supported. I say the latest ones because B&M constantly update their style as their technology updates. That way you can have the most accurate Supportwork.
Also, Dave you need to do that too. There are FAR too many supports in this picture:
I know how you love oversupporting your rides, but thats just too excessive. Its a B&M not an Intamin. The turnaround has way too many, take a look at the big turns on katun. And the same goes to your overbank:
You have like.. double the amount of supports you need.
Also your point about Alpengeist is wrong, Alpy is like that because of the massive size of its Immelman, and the height that it is above the river. Also its one of the older coasters, so it applies to my note above.
Now look at Patriots supportwork for its immelman:
See.
