Need FLEXIBLE Power Cord .


I am in dire need of a power cord with flex for an sub. I have some good Shunyata, ZU, Audio Art and Acoustic Zen cord but only my ZU Mother has any flex and its length is needed for my amp .Only good place for GalloTR1 sub precludes a "stiffy " .
In 300-500 $  new or used range at most .
Does anyone know if  cheapest Shunyata   has any flex ?
