Steve,
You might not find test lead wire in #10 or # 6. I suggest you all look at the MCMINONE website. They have excellent zip cord in guages all the way up to # 6 which is fairly flexible. It will not have the flex of "rope lay" cables but is not expensive of heavy. The super flex cables should be available anywhere auto stereo accesories are sold in your area.
