I'm with Rob here. The vt releases much better than the distel, and that's the whole idea of the high performance hitch. If it's not working for you, it just needs tuning.
I don't see any advantage in performance from a distel to a blakes. The distel became popular when used for two ended lanyards, and I can see it for this, but for a climbing hitch it doesn't perform any better than the blakes.
If the vt runs on you, you've tied it wrong. I pulled on different configurations and always got at least 1000 lb.s of holding, usually more. In other words, you shouldn't need a lot of wraps, your loop may be too long.
I will say the vt is for experienced climbers, actually I should say good climbers, beginers need not apply. In fact, if I need to tell you how to make the hitch work, you shouldn't be using it, so forget I even posted this.
