Re:
Being round and black/Dk-Grey they look much like the tubular Manganese steel version, don't mean to hi- jack the thread, but if you are after a carbon model, I have one of the handmade in Italy versions, with Carbon rails and shell, leather top, with Carbon insert, 195g weight and decent padding. These are £300 new, can do for £95 posted.
PM me if you are interested.
