There is a jungle of different vaping tools.
And it all comes down to personal preferences in the end, almost impossible to tell what another person will like to use.
If you can afford it I would suggest that you get 1-2 of anything that sounds interesting to try out.
Most atties dont cost that much per each.
I am not keen on throat hit myself, not at all so I am a totally wrong person to give advice on that.
But I have noticed that low resistance atties tend to give me more throat hit and for that reason I dont like them.
You say you like warm vape, I do to with some flavours, especially roasted chestnut.
The best atomizer for varm vape, and roasted chestnut, I have tried is a CE2 ultimate edition.
They could need a bit of modding though, howto you can read about on this forum if you are interested.
My personal favourite for the moment is the Tornado Ego-C.
It gives me excellent flavour, really good vapour and despite of the low cost for the changeable atty heads, £4 each, they last me for weeks.
Maintenance is easier than anything else I have tried.
For you maybe the lr versions would be better if you are keen on a lot of throat hits.
Unfortunately you cant get the cones separately yet, but they will come soon.
The new dual coil tanks are popular, I think people say they give good throat hit.
I have not tried them myself yet though, but a lot of people are enjoying them.
Anyway I think it is good to try out as much as possible, if for nothing else to calm your curiosity.
As long as you have a battery with a 510 connection you can always try whatever you want with it with a 510 connection.
otherwise you can always get a adapter for it.
