One tiny little problem with Enve 6.7's is if there is any play with the stem itself it will cause an annoying banging sound hence the need for a threaded stem with lock screw. The 80mm stem is a perfect fit for 70-60mm carbon's. I put a very small dab of thread locker on them and a few ounces of Slime in the tube and my wheels are both silent and bomb proof.

I was using these tubes almost exclusively for several years but noticed two consistent problems:

1. When inflating them with my Blackburn floor pump, I'd have to attach the pump at least 3 or 4 times before getting a good seal. I'd get it attached, start pumping and hear it leaking out from around the stem. Sometimes I couldn't get it to seal at all on its own and had to hold pressure above the valve stem with one hand (or a foot) while trying to somehow pump with the other. It wasn't until I tried other brands of tubes that I realized the problem was with Q-Tubes, not the pump.

2. The other problem occurred a couple of times out on the road with my Topeak RaceRocket pump. When unscrewing the pump head after inflation, it would also inadvertently unscrew the the removable valve core. Admittedly this is partially the fault of the pump, however it led to much cursing and the decision to buy tubes without removable valve cores.

Since switching to Michelin tubes with non-removable cores, both problems have been solved.

FWIW most of the 'Q-Tubes' I received were actually manufactured by Kenda.

                    It's a tube, the valve was straight, they look well made, they've been holding air like a proper tube should. The tubes I received were stamped as Kenda (on the tube, not on the box).

                    QTubes are one of the few fairly reliable brands that I've found for tire tubes. A bit pricey but worth it for for consistent quality.

                    Don't know how I didn't know this but these are Kenda brand tubes. I have never had much luck with Kenda but these had the stem length I needed so they work so far. Not a fan of threaded stems, they eat up pump head gaskets.
