Jumpers for Verity Parsifal Encore

I'm currently using the factory supplied jumpers and looking to possibly upgrade. I  am using Acoustic Zen Satori  speaker cables.
Verity wants $240 for upgraded jumpers from them and from what I've found on line, they supply Discovery jumpers and $240 seems high to me. I found some about 10 years ago that paid $70 from Verity. I can get Satori jumpers from The Cable Co. for a lot less than the jumpers from Verity.  Am I better off matching my cables? Do the 6 inch jumpers make much difference?  Is there some other options I should be looking at? 

Thanks
Jeff
