I used to own a set of double shotguns with jumpers. Wonderful cables. I’m going to bet you’ll never come across a set of just the jumpers as Paul really didn’t advertise he made them and probably most stayed with the factory speaker straps. You can make your own easily.
Paul used 18 gauge dead soft silver and did not use any insulation jacket but each single conductor was in its own tech flex sleeve. His trick was air and not an insulator which all change the characteristics of the cable... some soften too much and some make a cable bright. Pick up some Cardas silver solder, some black and red heat shrink and some affordable spades or bananas and you’re good to go. Make them 8” long with 3 conductors per jumper and they’re not twisted. I found the link to the set I sold so you have a picture to go off from. Paul also didn’t buy into expensive ends but less was better approach. Hope this helps.
