Simple copper speaker terminal jumpers? Lost my originals.

Can anybody recommend simple, but good quality, copper jumpers that bridge the bi-wire terminals?  I mean just the little piece of copper with the openings on each end.  I see the Cardas ones, but I don't understand how you can adjust them for the distance between the terminals, as they seem to be a solid piece.  Can they be bent a bit to make them fit?  Any other suggestions? 

The reason I'm asking is that I seem to have misplaced the original jumpers for my speakers and I found a set lying around the house that seem to have been from different speakers and don't really fit completely onto the terminal posts.  Also, they look more like brass than copper.  So, I'd like to try a different jumper.

Also, I currently have the cables connected to the HF terminals, but I saw on some threads here that people were connecting the cables to the LF terminals and jumping to the HF.  Which do you think is better, audio-wise?

mtrot - Here’s some info about "single-wiring" options for bi-wireable speakers.

Personally, I prefer to use very short lengths of the same cable that's running from amp to speaker.  Several manufacturers (e.g. Wireworld) make these as standard, and others (see above) will make custom lengths.  But it seems to make sense to me to use the same conductor.

mtrot,

I have a set of Amadi Maddie Signature silver wired jumpers that are 14" long and have good quality bananas on all ends.  These have very good detail, dynamics and clean, deep bass with NO etch to the highs.  I could sell you the pair I have for $75 if interested.

6 inches of Copper is 6 inches of copper, nothing more nothing less, no matter how much you pay for them.  The key is to minimize the resistance between the posts.  So... nothing can be better than making jumpers out of 12awg or 14awg copper wires.
As someone mentioned above, audioquest as some silver links for $25, it's expensive and only 16awg, but silver is a good conductor.and it is an easy fit in your posts' holes.
Ask any engineers (not sales & marketing) working for reputable speaker manufacturers and they will confirm that the jumpers do not degrade their speaker performance.  Start with Harbeth, They're not deaf, and they have very revealing equipment to listen and tune their speakers.
A little fun does not hurt:
