Newer rtas have juice flow control, air flow control rings, you can remove the deck without draining the tank, top fill, turning off juice flow, top fed decks. The designs have gotten more flavorful with newer chimney designs, juice flow channels are tweaked and redesigned. It's like every version gets better than the last.
Basically, dripping is convenient and flavorful, right? Rtas are getting more convenient and more flavorful than their predecessors. So if they remain on that path, they will be able to handle more power, be easier to maintain, and create awesome vapor.
1: Juice flow control:
There are a few rta's that are supposed to have some sort of juice flow control
............ was just checking
I have a rose v3; the rose v2 is supposed to have juice flow control; when I was ordering, I saw there was a rose v3 so I ordered that one; turns out the v3 does not have juice flow control. That's an example of a newer rta not having juice flow control even when the earlier version had it!
Bottom line: of all the rta's I have so far, none of them have juice flow control.
2: Airflow control rings:
Airflow control rings are useful when the airflow fundamental limit is wide open; then you use the airflow control ring to reduce the flow.
I have 1 rta with a useful airflow control ring: a "Heavy Taste mod-60", which 4 hole sizes which could be 1mm, 2mm, 3mm and 4mm and it's a twist lock/groove arrangement when your turn it and it falls into a groove and stays in place, and for each hole size there are 3 holes 120 degrees apart; That's the one airflow control arrangement I've got that's actually well implemented that I use.
Most airflow control rings go from : now wide/open enough, to tight/closed
3: You can remove the deck without draining the tank:
I can do that with my
- flash evapors which I use
- herons, which I dont' use
- heavy taste mod-60, which doesn't hold enough
- bigD v1 which I use sometimes
- bigd v2 which I hardly try to use so far
4: Top fill:
hmmmmm ; nope; none of my rta's are top fill; Used to top fill my kayfun3.1 but got tired of that hassle.
There are innovations/improvements in rta's but take the kayfun v4 as an example, I still haven't ordered one yet after all I don't want to continue ordering some other tank just to try out and not end up using or maybe there'll be a major issue and there'll be a kayfun4.1 or a kayfun 5; actually I happened to scratch off the kayfun4 from my wishlist just last night on fasttech and added the 28mm kayfun4 version instead - there ya go - good thing I waited.
And dripping is not convenient; the reason I drip is the rta's haven't been good enough; but at this point I'm using my flashevaps more; best compromise.
I can see modular boxes in the future that resemble REO's
