Allways use a piece of you speaker wire.Use the same cable so it does not change the sonic signiture of the cable.
Custom jumpers?
Are the stock gold jumpers for Bi-wirable speakers any good? I was wondering if short runs of high quality speaker wire between the posts would be better? Of course there is the possibility that I'm a complete weenie who thinks about this stuff too much and I should just not worry about this kind of crap!!!
