Arkio-
I have not tried the umbilical upgrade so can't comment. However,the cord to use earlier in this thread was the Moray James 1.5. Hard to find used,the latest 2.5 version is what I'm using presently on my Syrah. BWhite said that he could recommend the 2.5 as being either equal,or very nearly equal to the 1.5. That said,the 2.5 on my Syrah replaced a Black Sand Siver Reference III. Either one works great on a Syrah.
Hope this helps.
