I actually like the single chamber more. These opal marbles are nice and could be also functional for lifting the tube.
But the marble on top of the perc - it looks cool, but imo it's the worst place to have a marble on when you drop the tube. Imo it would make breaking the perc off a bit more likely. But I think the turbine toughens the perc a lot, overcompensating for the marble.
Single chamber is also much easier to work with, to pack, and to clean.
When I saw the final prototype of the double chambered one: Why a showercap? I know there are a lot of lovers of this perc. I just think its not the best idea for a HT, especially in a double chamber.
Caps in HTs are bound to be tiny, therefore requiring very little water and giving little diffusion? Double chamber is to boost up diffusion to a new level, so why build it from low-diffusion percs? So it isn't too much? ...
Also I've had my theoretical concerns about water clearing and accidents. With these old Swagger bottom guards it would be easy to overflowed water to drip right down in the Cloud. Now there is that new umbrella one, so that should be okay.
Another thing is pouring out the water - sems to me a showercap can only be completely emptied only through the bottom - as it is an inverted showerhead, which pours out through the top.
But down there there is an umbrella guard, so how can you get out that last bit of water? But imo still better than if the cap was the second perc, then the water would be stuck between them.
These are all the reasons why I like the single chambered one more in my opinion. Yet I can also see why did they choose it:
A showercap definitely makes a wow factor, it looks crazy.
Two identical showerheads would not make a wow factor at all. (But imo functionally this would be best option)
Trees are loosing their popularity.
...Any other vertical perc exists? I don't know of any...
Now as many other low level contributors I wish I had the money to level up to the Early Bird. Well, too late. You Birds and Fanatics are going to get some sick tubes!
Also - Fanatics, don't taky my words too bad. it may look like a big list of cons, actually these are only few tiny theoretical issues. I've never even uses any cap. Even when I think a cap should better be in a regular bubbler like the famous SYN one, these double HTs are still awesome as hell.
