I feel stupid for forgetting about this one, but a recent article has jogged my memory.

Ross 128 probably is more iron-rich than Sol, so Ross 128b probably has a large iron core- that means it will be a little smaller and denser than Four's estimate, with a gravity a bit higher- say about 1.15 gees. It is unlikely to be a carbon world.
I think I can edit this together into a suitable article in the near future, unless I forget again.
