One aspect that needs finalising is the choice of knob. After much searching and comparing, I've whittled the choice down to two options.
This has a very clean black-on-black look, with diamond-cut lines on the top of the knobs. From the Cliff website:
Knurled aluminium shell on plastic inner. Standard finish is black anodised to a very high standard.Nice.
