Well, as I previously noted in this thread, I had terrible trouble using the Ego tanks with the GTUS, with the main problem being juice eventually working its way through the tank and into my mouth - I really hate that. Some reduced flavor, too, but that's not as big of an issue as the juice-in-mouth problem. Anyway, I decided to give the "Quigstick" a try, and low and behold, it seems to have solved the problem of juice coming through the tank. I have run about 5 tanks worth of juice through the GTUS with no issues whatsoever. That's great news to me, because I really wanted to be able to use the Ego tanks, and now I can. I guess that cotton just holds onto the juice better than pure SS. Flavor is good, too. Probably not as strong as the pure SS, but I can live with it. THANKS QUIGS!
