I saw the show off thread, and now I'm jealous. How do i go about getting the correct tech flex size and heat shrink to get this stuff to fit 14awg? i poked around and have picked out all the stuff, and colors, i need, i just would like to know sizing so that i can order it up. also, what are the advantages of spades over bananas? my bx1's dont really seat well with the banana plugs in the binding posts. thoughts?
