Speaker cable Question?


I have a 8foot pair of Analysis plus oval 9 cables. I have a pair of JR-201 mono's. I don't realy need 8-feet of cable, 4-feet will do just fine. I want to go with a Cardas cable.
My question is do I need to stay with 8-feet do to the resistants of the length of the 8-foot cable or can I go with a 4-foot cable and still get the proper sound?
Is there a reason why people use 8-foot cables most of the time?
Thanks

I am using a 36" Ridge Street Audio- Poiema speaker cable and they work great! Don't spend any more money than you have to.There are others that may say you have to go with a long speaker cable,but I am not of that camp.
the thing about using shorter custom lengths is when the upgrade bug bites you again you are limiting the number of people who might want to buy your used cables.
Thanks for the advice gentlemen. I am even thing about trying Anti cables first to see how these work. I guess I am curious.
