I only use the texas-Tuff. I had a ego 1100 and they recommended the Lr,but I had better luck with the SR. I now use a Vamo and still use the SR. You will love the tank. You may have some quirks at first,but once you get the hang of it you will not want for anything else. Ray @ Valey Vapes makes the Tex Tuff for vape dudes and he has a good deal on Cartos-pre punched,when you buy 5 or more boxes.
