I’m pretty sure I’ve got a Wasp Nano coming my way, so I can take my time, do more research, and maybe plan on getting a couple RDAs over the next months to try out. Unless I fail right off the bat 
Now about Jai, and this is not a reflection on you in any way, but I feel several of his reviews are biased enough that I quit watching him except for amusement purposes. ALL the reviewers here on ELR i have much trust in and they go into their review with neutrality, truthful and unbiased. As I feel everyone in this thread is also doing.
And I don’t think all Joyetech devices are fantastic, but I’ve watched Jai smash them just because he does not like the company. Anthony is another reviewer, that because they cannot give a honest review, I have lost my faith in their reviews.
I appreciate all the advice everyone here is giving me. I really appreciate y’all as my family!

Haku has an interesting build deck and airflow, and the notches to position the coil. I remember it.
