ph- Thank you for the indepth, detailed post with picture; I love it! Its great when people take some time to contribute worth wild posts that provide information that can be used and benefited from. Let me encourage you to continue these great posts.
Glad you like them! I love sharing knowledge with others, and it seems that the best techniques for vaporization are still evolving. I even have a bit of a skunk works project going on to create the next generation of vaporization technology, but it's still in the early concept stages.

Now for my questions. This is but a thought and not an attacking statement, but I'm thinking that all those screens may be a bit overkill. I say this as like I mentioned above I use a mini whip in rotation with my ezchange and it sports the classic setup of using a single ss screen. I have also previously used a regular sized classic whip and with both I have never had issues with sucking particles into my mouth. I am sure that some tiny pieces do get through, as you can see a few on the wall of the wand, but I never realize them being inhaled.
Thanks for prefacing your statement, but I'm always a fan of constructive criticism.
In a way, you're right, this is definitely overkill. I'm very, very sensitive to particulate pass-through, as my reactive airways will often trigger major coughing fits from even small amounts of inhaled particulate matter. I can't stand cigarette smoke, dust, strong cleaners, etc. Cannabis smoke was a necessary evil, but between my VB and my VaporGenies, I only combust the occasional joint, hash, or oil.
My standard VB whip (with a single stainless screen), after only a few days of use, had a heavy layer of fine particulate built up all over the inside of the glass handpiece, and a decent amount spread throughout the rest of the whip. I could only vaporize to about 60% of my normal temperature, as anything higher needs a finer grind, and was pulling through enough that it really hurt my throat.
In my VaporGenie, I use three stainless screens layered right on top of one another, each one rotated slightly to catch even smaller bits.
There's a substantial downside to this fastidious technique, however... any such scheme is bound to clog up sooner, which requires increased draw strength, and sometimes causing herb combustion (if the draw speed is forced too low). As a result, you have to clean a lot more often.
This compromise is reasonable for me, but probably not for most users... but if you're sensitive to the particulates, there's not really a choice... you could use a hydrator or other water piece, but I really like the flavor of straight vapor and the control it gives you when pushing close to the upper edge on temperature.

I can see the logic behind your setup, just like one would use bubble bags; ensuring that in the end, you are getting only the best product, in our case NO particles. Have you done varying tests in screen combinations; ie. 1 ss, 2 ss, 1 ss 1 ceramic, 2 ceramic? If you have, what were your outcomes?
I have, and I'm still experimenting. The setup described above is clogging faster than I would have expected, so I'm going to do some more experiments and see if anything else works better. In some ways, the smaller screen diameter of the EZ Change Whip (and corresponding smaller surface area) makes the screens work more efficiently, but they inherently clog faster (since there's less surface for the air to "get around" clogged pores in the screen).

I also have a inquire to the types of screens you are using, as under bullet point b. of the ceramic statements, you mention giving the screen some rigidness. I currently use the ss screens sent with VB products and they are pretty sturdy and I have never had issues with bending out of place or anything. This may also be in part that the screens I am using are chosen by VB to be used with VB.
From looking at the screen in the standard hands-free VB whip, it appears to have a coarse weave with a relatively large wire diameter when compared against other screens. This thicker wire is much stiffer than the wire used in finer mesh screens, and resists bending... which is why they're such a pain to work with.

Another aspect that I may suggest that you look into is the size of your screen. VB sells mini screens that are suppose to fit the ez change, as well as the mini whip. I purchased these but haven't tried out how they fit yet, but I am assuming that since VB sells them, they prolly fit perfectly or closer to it that another companies. I do not have access to my VB and stuff, as my mother is visiting right now and I don't partake when shes around, out of respect to her. I am interested in your thoughts on this.
I didn't know that the mini-whip screens are the same size as the EZ change whip... I'll have to order a few of the mini screens when I do my next order (my LHS doesn't carry most of the VB accessories). I might try a simple 2 or 3 layered stainless screen in the EZ Change without any ceramic at all and see how it works... that's the sort of configuration I use in all of my VGs, and suspect that it'll meet my needs here too.

p.s I am very glad to see this thread getting a bit more attention from people. As you can tell I love my VB and love discussing aspects of it. Let us all please continue sharing and reviewing and discussing out comings and goings with the VB... though I may say that maybe this thread doesn't get as much attention as others as the VB is simple to use, very little issues to go wrong and overall a great product... (this is my opinion and I am not looking to start stuff with what vapes are the best and better, etc...)
Glad to be part of the Vapor Brothers family.
