No matter what studs are chosen, they should all be the same. Now the only question is, are there studs that offer superior characteristics?

Henry,
I absolutely agree - completely crackers and having been involved in hot gas turbine test stands for years I find the concept of mismatched expansion rates of studs bewildering.
There must be all sorts of ugly 'out of round' issues to worry about and it can't help the longevity of integrity of the CE Ring.
