Contacted DH-labs directly, they sell direct. The techflex is available at a variety of places, heatshrink.com is the link they sent me but also mentioned others. I've ordered it from a place before as well, don't remember where though.which place is this? since my move, im also looking at new cables.
They mentioned they'd only done it one time eight years ago but didn't seem too put off by the idea. Somebody had the same request but they'd used all the white tech flex they'd had.hey great to know that dh-labs works like this. i may wait to hear how yours goes before placing an order.
