Oh ok... so now i have to figure out how im going to put my scubgen on the darwin... Might have to grab me one of those goosenecks.. Is a gooseneck an essential to a darwin?
Personally I don't like them and I now have 2 with one defective

. Emailed Cheryl at TTliquids and have not had a response back. Will give her one more shot next week then I am going to file for a charge reversal.
I got 2 because I had one and that was just not working at all. The whole top heavy thing doesn't work on a flexible tube, seems logical, but everyone said to get one if you have a tank, so I got one. I figured the size as wrong and got another one in a different size. Besides it not working, it doesn't help with the whole top heavy thing.
For me, I throw the tank on the Ego Booster if I am going to need to close the arm. I think you can try and pile on a ton of adapters and see if that works. I saw a pic of someone earlier in this thread getting that to work with a long grouping of adapters.
