I've been following this GB from a few months back, and I have to tell you that I'm pretty much 100% set on buying this set no matter who makes them. I would even say that I'm looking really forward to it if its JTK because I heard they do triple shot ABS. Anyways, idk if my input would matter at all, but I just wanted to say I love this set and I would buy it whether it's GMK or JTK.
