Hey just like to chime in.. I'll be purchasing my 3rd glass tooty just now. No carb this time. Now I'll have 2 without holes and 1 with.
On another note. Here's how I do my thing 'now' after evolving into a different setup/routine. DRY herb a MUST now. Real Dry. Because before I would NOT use a kief catcher when grinding with the idea that the kief will be in every hit as needed. Buuuuuuut after switching back to the kief catching method where the user puts the kief on the tip after putting the herb in 1st I found that this was a superior method due to less cleaning/maintenance. The reason Why? Because it seems when the herb is dry and has some of the pollen removed then placed AWAY from the screen it has less chance of build up. Plus gives you an option to do a little less strong hits if you opt to not put the kief on (good for morning). I usually put my kief on the tip after taking my 1st draw by itself.....fresh. Then for the 2nd draw I add the kief.
Also as per reading this thread, I am now loading EVEN LESS in the stem and finding the results to be not much different from a full stem, so SAVE ON! Plus even better is that I'm finding my bud is not getting TOO DARK, I prefer mine on the lighter side because for some reason I SEEM TO GET MORE VAPOR/Thicker vapor when you don't 'Milk' the crap out of the bud.
So, those are my new techniques after about a year or so. I evolved! Off to purchase that Tooty....
