I had a very long conversation with Steve @ Calmini quite by accident today, and he is more than glad to talk your ear off about the engineering behind his products. You've got to have some idea of what's going on, but if you do, he can gel it very well for you.
I'm pretty convinced this one was done right. If and when the time comes for me to beef up my steering, this is the answer, hands down. The price certainly doesn't hurt either
