Ski, that's my kind of party! I think I'll fit in here nicely
Since I have a Darwin on the way, I'm hoping you all can provide me with some suggestions. Right now I use carto tanks a lot, so if you could suggest something that will allow for the arm to close without too much extra hassle. Was thinking about trying Visions or the A2/A2-T. I'd really appreciate it.
Vision Extreme and Giantomizers close on mine. It's a tight fit with only one extension, easy going with two (or one longer one). Having a couple of extensions stacked has always been enough for me to screw on anything 'ego sized' I've ever wanted to try without risking scratching up the finish. The threads when stacked that way have just enough play in them for much of that ego sized stuff to close.
The stainless CE2 dual coils@3.5ml will close easily...even with no extension at all. Because the stainless is quite a bit thinner than plastic (all stainless, not plastic inside windowed metal like the Giantomizers), they're pretty slim. So far I'm pretty impressed with the performance of these.
I usually keep a 510>510, 510>901, 901>510 series on mine. I know that's alot, but it's mainly for convenience. I've always got everything I need right there at hand (I keep a 901>801 on my 801/302 gear). Another added benefit for me with that stack of mess I keep on mine is that I can really tweak out my air flow by adjusting the threading of that 901>510 (or 901>801/302 if I'm using that setup).
For the bigger tanks if you must be able to close the arm, Totally Twisted offers a goose neck @ $20. I'm told they'll make you a shorter one if you ask for it. I've found in situations where I'm willing to haul around something as big and heavy as a nice tank (a long drive or sitting around the house), I don't ever close the arm anyway. That button is NOT going to misfire on you.
