Congrats on your (almost here) new toy
@flyfishwino ! Sounds like it couldn't arrive at a better time.
Since I just got a gh scoop from
@Ratchett, I've just had the chance to play with a packing method different than I typically used.
Bottom line is I think the gh is very forgiving.
Regarding grind, I use a Samta Cruz grinder and that works great. I'd call it a medium grind. But I know some here don't even bother grinding material.
Regarding fill amount, personally I typically fill it about 3/4 and BARELY tamp it down.
Before the gh scoop, I pinched ground material into little balls and just dropped 2 or 3 in. With the scoop, I leave it nice and fluffy. In my opinion that seems to work better (less draw resistance, but that MAY also be due to a recent mouthpiece cleaning...).
Regarding temperature, I prefer 3 and tend not to step up, but I may be in the minority here.
I think you're going to have to experiment to find your sweet spot.
A couple other things... Avoid putting your lips on the very tip. It can get pretty warm. I suggest you place your lips at the very end of the taper. I also wait until the gh is completely cool before taking my next pull.
Last is accessories. I highly recommend an external charger, extra batteries, and a few of
@Ratchett's goodies. I have and love his leather case, gh spiral stand, and the new gh scoop (I don't know if he's named it yet).
Keep us posted, have fun, feel better, and be diligent with your physical therapy!
