Kurt, I mounted a similar front rack on my folding Dahon and experienced the same emotional response. Whoa! Something is not right! The rack points in one direction while the bike turns in another. It is very disconcerting at first.

How did the suspension system work?

My AM hub shift cable also has a great deal of slack in high. But if I try to adjust it out, shifting to neutral and low becomes lousy.

I'm really digging your Moulton. A Brooks B17 will be a great addition.
