The hotter e-liquid gets the more the flavour suffers, yes mesh heats up very quickly and gets very hot but it means it needs lower wattage and where it has the advantage although it heats very quickly it cools in an instant so the e-liquid it'self in the tank stays cooler and keeps it flavour.I high Nic low W the Gemm25 pod of .ohm5 too. Epic flavour on restricted DL and I also MTL the .5 pod its good both ways
Another ingredient for flavour is surface area of the heating element and mesh just has so much more surface area than a traditional wire coil. Also if you look inside a commercial mesh coil now the mesh isn't mesh as we once knew it but more and more metal is on show as they go for even more surface area some manufactures like Innokin even both serrate and laser edge the edging of the mesh to increase the surface area still further.
These new wicking materials championed by Freemax and Horizontech, using things like wood pulp and Flax mixed with cotton and the latest Tea Fiber just seem to give less if any taste so you get a purer taste of your e-liquid, the other added benefit is they seem to hold the liquid much better so much less leaking!
