I use a 30mm, even on my smaller pieces...and I'm not trying to go back to 25mm if I don't have to. Even for smaller dabs (which is 98% of my dabs), it's great!
Sounds like you are looking for perfection of YOUR preferences.
Not a good idea to assume that everyone else's idea of a perfect vaping experience is the same as yours.
Different people have different priorities and different tastes.
That HydraVonG Deluxe pack on sale right now with the Bubinga stash is very tempting!
I knew there was a reason my VAS sense was tingling this morning :smug:
