Yes, 60/40 could even be a good intermediate solution… You know, for DL they usually recommend 70/30 by default because the extra VG is responsible for more vapor + you know, the VG-heavy base liquid is thicker, so it flows less easily too.. For MTL, 50/50 is the basic recommendation.. or even PG-heavy…
But for example, I mix around 50/50 for DL too, the reason is simple: PG is responsible for the flavor, and I’m not that interested in a large amount of vapor.
