Have heard good things about knukonceptz but haven't used them personally, they are popular on the other forum as well.
I've been using the Stinger 4000 for myself and friends installs for quite awhile. Very convenient 18" length, quality cable but very thin and flexible for easy routing, ends grab like a bear and have never had one vibrate loose. Switched to them when the stock BT cables vibrated loose a couple of times, I believe BT is now providing them with their amps as well. Easy to find on amazon and pretty cheap for the quality/convenience. Stinger also makes 6000 and 8000 series but much more expensive and the 8000 are way too stiff for routing around a fairing.
