I've got a fuel and it's very good, I was torn between the fuel and an armotech. The fuel I suspect maybe made by armotech, as it has 'armotech' written on the fuel bottle next to the thread info. The fuel is 10 year life, hydro every 5. The fuel is very light and not had any bubbles between the composite layers I think due to the stainless inner. As for the reg, I've got a ninja UL, it's not let me down yet. They have an excellent reputation and I like the double o-ring. I've got the 1.1 ltr but this was down to the length of my arms, any smaller would have been uncomfortable to hold.
