First off, packing the GH isn't too bad, the chamber is almost as wide as the unit, so its not something like the V2 Pro S3 which has a very tiny and cumbersome opening to pack.
Now I did try your the joint method, unfortunately I only had peach flavored papers so it threw off the flavor and I couldn't tell if unflavored papers would also do that, or if it was only caused from the flavored ones. I also noticed with this method that Air flow wasn't as good, and the AVB wasn't quite as even.
So in the end, this does work, however its probably not something I will be doing again.
