The new heads & atomisers all have SS & Ti stamped onto them so there's no issue with recognising those.
I'm not sure but I don't think they've made a Ti atomiser until recently, I still have to buy one to check it out but I imagine the top half of the Ti atomiser would colour up whereas stainless just turns a slightly yellow colour.
I have both stainless & Ti heating elements but I don't notice a lot of difference.
I'm not a big dabber but I agree with the
@herbivore21 comment that sublimate can be pretty gross, it's like extremely strong reclaim & I do have to clean the atomiser once a week or the taste suffers & the draw can become restricted.
However this happens with all my other vapes as reclaim will build up, it is yucky & does need to be cleaned or it will affect performance & taste.
The Sub is my daily driver & performs fantastically with whatever I put in it.
I have no need for more vaporisers which is a great feeling but it's always nice to browse the sales because different vape signatures are fun.
I love the fact that I don't have to suck down a heap of hot air just to get the vapour flowing, we shouldn't really have to do that now.
The Sub milks up any tube instantly with incredibly thick vapour & that's why I use it.
I also like the fact that there are other Sub styled vapes available now as I think it's a great concept, but until I find something that performs better than it I'll probably just keep raving about it.
Oh yeah I also have to thank
@Teedub for his suggestion a while back of using denim for unscrewing hot atomisers & heating elements. Awesome suggestion mate this has saved me so much time & I have dedicated an old pair of jeans for this, thanks man.
