SOLO PVHES STEM MOD

I love the solo but desire a bigger hit (clouded or cloudless). So, I went ahead and have done did it. I used a carbon tip drill bit I bought at home depot to remove the glass segment containing the holes in the PVHES standard bent stem. This is the first time I've drilled through glass. I expected trouble and sure enough, some trial and error was involved. Without getting into the weeds, I was able to entirely remove the glass and shave down the remaining shards to make them harmless.
I should mention...
WARNING: WEAR PROTECTIVE GLASSES. WHEN YOU DRILL GLASS, BITS OF IT FLY OUT AT YOU.
Since then, I've vaped three stemfull of herb. In the first, I used a standard grind and packed it very lightly. For the second, I grabbed a nug and shoved it down in shaft, packing a bit. The third and last attempt, I recorded in the photos below. I used a slightly more than standard grind and packed it from the screen up to where the glass used to be. Oh, I forgot to mention, I used those NO2 screens with the round divot in the middle. With some futzing, I got it to fit perfectly in the narrowing point of the stem. I packed firmly but not overly so.
Packing seemed to work out better than dropping the herb in less densely. I was able to get some excellent, fat vapor straight through the stock stem at 4 or 5. I went through my water piece at 6 and 7 (to minimize the heat) and ended up getting the most bang for the buck. I was able to go on for quite a while with extremely flavorful hits. By the end, my ABV was entirely dry and dark but clearly not burnt. I couldn't say exactly how it is different in flavor and pull. But there is surely a dose difference, merely from having more in there. Also, I think it might perform efficiency and flavor wise a little more like the standard whip vapes that have hotter temps but more room in front of the heating element.
More experimentation is necessary.
Again....

EDIT: Maybe, I should paste the pics in instead of a link. 8 or so pics seems like a lot tho.
Here is a video of me using the stem. You see some cloudy vape in the apparatus and a few wisps being blown out by me. The video or the angle didn't capture the magnitude of my exhale, for what it's worth. Nevertheless, I shall post the video.
