I'm still not sold on the FW6. I find myself reaching for every prior version I own, even after kicking up the temps.
I just shopped Delta3D recently and didn't notice something for the FW4. Now I'm going to have to go look. I'm assuming it will work for the FW3 as well?
The FW 6 is my first one but it has has grown on me. I started slow and sent it back and it took me a while to use it much because of an asthma flare up.
Eventually I modded it with an upside down basket screen and use it at 360-370-390F. I might even drop the #3 setting to 380F since I never use 390F.
But now I use it the most of my herb vapes. It has the best flavor, but its not a heavy hitter, but neither am I. I fill it 3/4 full (the basket screen reduces the bowl size a little) and start hitting it at 370F, then after two hits drop it to 360 for a few more hits, then stir and add more fresh herb. My favorite part, for whatever reason adding more fresh herb seems to coat my mouth with terpenes. Even when the herb is dark it doesn't taste burnt, just roasted like coffee.
That FW 4 must really be something, lol. Ive been considering other convection vapes,
(tiny might, tetra p80) but when I think about it more, a bigger hitter isn't really where I'm at now days, and the FW 6 suits me fine.
