Have you decided how you're going to tension the chain?
If you go for an EBB be careful which style. The Van Nicholas has a wedge type, I nearly went for one of these, but there are plenty of reports of them creaking. The type Thorn use with the set screws isn't such a good idea in a titanium shell according to the builders I spoke to, they said there was a possibility of the force distorting the shell. That only leaves the split and clamp type, there's a picture of one on here somewhere, it's what the builders for Singular are doing, I'm sure it's fine if the welding is good enough, but it does look crude.
It's worth a bit of research before you commit yourself.
