Yeah that is not a grid, that is the frit disc, it is an evolution of the honeycomb, instead of a flat disc with punctured holes, it is actually a disc made up of glass pieces, that are melted together, so the holes through are completely random shapes and sizes, as air has to squeeze through the little gaps in the pieces of glass fused together... Sort of similar to how pearls work to cool vapor flowing through their crazy cracks and crevices... The one from that manufacturer is pretty nice, especially compared to other Chinese frit disc pieces, they use a pretty coarse frit, larger smooth pieces of glass, sort of little pebbles, it is a nice piece with nice function and it is quite stable, large base compared to all the other ones and decent height, volume, mouthpieces alright too... Compared to a matrix, it doesn't have the same airy flow, so it is better milking, however there is a bit of restriction for that first hit to get going, a little more than with laser cut FOL but I think once you are inhaling the flow is great with strong bubble stack from the suction
You mean a straight tube bong with inline matrix? It could work fine, I just would never buy it, now that I know I don't like that for vaping personally... Yeah that 8-9 inch tall short fab is what I was talking about, like the new one from SamL there are a wide variety of them from different places with different percs
I think we have a miscommunication here, milking really has nothing to do with what you describe, milking is basically how well a piece shows off the vapor filling it, so for example in the Fab and Swiss pieces, because the flow is disrupted by the glass obstructions and extra pathway, it changes the way it milks, you might inhale more of it instead of it milking the glass you see, that is why shower head facing down does more milking quicker easier compared to fountain facing up where you are inhaling more of what you are milking, you see?
So it is not just volume but surface area, there are different opinions of having the extra volume means cooler vapor, certainly good with a baller since they can produce so much thick vapor, but like I want to be able to clear the piece comfortably you know? Surface area also is more obstruction and places for the vapor to condense but that can cool it, like spikes in the pathway, why you don't even need water necessarily if you are catching the particles, right angle bends and swiss holes are extremely effective this way...
Water itself can condition the vapor, also could cool it in some senses, there are varying opinions and getting a piece that is fabby or full of Swiss is a great way to buy a rig that will be two in one, good using dry and with a bit of water for a different type of experience... I do prefer to use a little bit of water with most of the ballers and like my tetra because that little bit of conditioning really helps even if it is only a little bit of water before more dry pathway (with more water loaded, complex dry pathway from Swiss holes or egg can become part of the perk, we call that natural perk, like if there was a right angle joint but no perk that would be a natural perk, which is how a lot of the disc rigs are made, which makes them a bit trickier for most vapes in my experience, so the inline style is preferable imo)
