Sorry to hear, not having much luck with these RBA's

I just made up another RBA for the crown for some new juice. Bought some more cotton too whilst at the new cloud chaser shop near me........(oh dear,will have to be very careful!!!) . With the coil and no wickj, have you fired it a few times to make sure it heats from the centre out?. I find it a very responsive coil and pretty much instantaneous . Around 4mm strip in width, thread through and trim to a little past the base, can soak now or later,then position wick ends up or fit under cap(if up then fit cap and then push into place ). Another few drops of juice,fit tank,couple of draws without power and should be good to go. Too much wick could also be an issue,maybe a thinner strip still at 3mm and try that.
The crown will not work on the mini sub units due to it being 0.25 ish ohm,the dna40 will pick it up or any device down to 0.1ohm(most new ones seem to go that low now)
Check gap under coil, ideally around 1mm to 1.5mm
Maybe the % of VG is not high enough, i am using 70 or 80%(most i can get due to flavour being PG)...........Just a thought
Also are the air vents fully open and a strong draw to the lings to aid the vape.
Reg the needle ,yes it just allows juice to flow better and no doubt be corrected in future coils. Would use a small needle at 1st and do a single hole to try out because if too far it will just flood and no going back. Least you can work it around a bit if it does not make any difference at first.

Just tried out one of the 2 new flavours.........not cheap either at £9($15 ish) for 30ml

and filled my spare crown and RBA tank
Very nice and......well for special occasions with that price :laughing:
Probably by a couple or so bottles every month or so to try some more flavours. Some really nice ones, next one will be a sweet one thats like a tutti frutti type with immense flavour..........really like that one too and all dripper bottles. Had a good long vape chat with the owner who is recently got into dripping. His reasons are simple, easy and quick to change flavours over emptying tanks out. Of course a huge intense hit of flavour and huge clouds........... He is going to knock me some coils up , learned something with the gauge as i use 24g or 26g. When you use 32g for example it heats up a lot quicker so get instant hit/vape/clouds. Also pre-twisted kanthal which holds the juice better=better flavour. So i have a good way to go on this journey yet
I had a go on his dripper, £20 clone which is for sale with 0.5ohm coil at 71w...................simply astonishing. Instant warm vape with the most flavour hit i have had. No nic in it at all...........awesome vape!
So out and about tanks (RTA)and maybe drippers for in house use so have a few set ups dedicated for a specific vape experience
