If your happy with your current cables for now just get the same jumpers. Anything is better than the supplied jumper bars most companies provide. If you can't find what you want from AQ at a reasonable price then these work great and are OCC copper. Also the price is only about 75% of what's listed in US dollars. Can be terminated however you want them.

I use these speaker cables in my FR system.
