No, I get the same vapor overall. You may have slightly less dense hits, but will have more hits in total to make up for it. Really bro, if you don't want to upgrade your grinder, just make less turns with the grinder than you normally would. This will provide a less fine grind. I do this all the time when I want to vape my kief right then instead of collecting with my space case. It's so simple man. I've never had abv in my cooling unit and I use the default screen instead of the fine one.
Don't you feel you get less vapor from coarse grinded nugs? When I tried that I didn't get vapor for nearly as long as when the bud was grinded
When I was using the regular coarse screen with the Orange grinder they provided which would seem the proper way to use it, I literally had to clean it every 2 sessions because there was so much ABV inside. I mean I didn't HAVE TO clean it but there was ALOT in there. So the only answer seems to be use the finer screen or oil pad which i definitely don't want to do as I like the free flow and an almost fully packed chamber or deal with cleaning up the ABV or use a coarse grind but then not 100% of materal gets vaporized as I do notice a reduction in session length and vapor amount when using coarse grind vs fine
