Binding Straps vs Jumpers

I made my own Jumpers out of Home Depot multi stranded 12awg copper wire. Which worked quite well and were an imporovement over the Aluminum Bar Jumbers provided by Focal. Then I ran into a bargain set of Cardas jumpers which were even better, I think so anyway.
As for worth it ?? I would say yes if small to moderate improvements mean anything to you and of course you think the price is in line with others. If you want a recommendation I love Jena wire which is what I use for speaker cable. The jumpers are called the Dussys I believe. They are not cheap by any stretch.
I agree with Ncarv here- is this hobby worth it? It appears, that as a general rule, that even a small improvement, is important to most people who are into the hobby.

Thank you all, as always thoughtful advice at the GON. I shall dive in yet again. Happy Holidays!

My panels came with Chrome Plated steel jumpers.

I replaced them with #6 copper hand whittled into shape....the #6 was just a touch too large.

Nice help....and even though it my be psychological, I feel mucho better knowing that steel is out of the circuit.

Next step?
Remove 'em altogether..and the fuse as well.

Dotto what Elizabeth said. The question is, if you can bi-wire, why aren't you already? Then again, you could take the next step and bi-amp. As long as we're blowing money unnecesserily.
