have you tried the smaller PN bubbler one with the VB2?
Hey sticks remember the other day you were like what you talking mark? Well I was talking about using a 18mm female to 14mm male adaptor to use the mini water tool on the VB 2.0.
See the adaptor I have which I'm describing fits right into the VB2.0 above the small screen bowl tightly sealed( the stir stik screw on cap when removed there's a bowl and then the screen) it fits right inside the the rig where the cap screws on.
Now with this said I can put this adaptor on my VB 2.0 and use the mini tube, basically the same as using the adaptor but mine is glass. Now I was trying to explain that the small screen bowl for your also fit a VXH screen a bit looser but fits so I fill it about half and put it in the VB 2.0 screen chamber the glass adaptor has a screen inside it which keep the herb from flying out of the elb when drawing on it.
I know this soun like stoner talk but this really works well with this adaptor I can use the mini tool or add a 14mm female to 18mm male and then use my hydratubes since I don't have any TVB glassware but this works great for me.
I would say that milking this unit is possible and ya the water tools don't overwhelm you with vapor but clouds big enough to medicate you are there, and bigger cluds are possible depending on the technique you use.
Slow sweaty draw you can't draw to fast or you will cool the heating core to fast and hinder vapor production ill put up a video and show you what I mean and how my set up looks like since stoners like picture and videos lol i know it all sounds fucked up but hey use your imagination. I have a video loading right now using the VB 2.0 with the mouth piece a quick tid bit that I did a while ago before I got my pinnacle and it hit the shelf but I thought I'd share and make a other video with my adaptor and vb2.0 in action.
With this set up I didn't have to buy a adaptor or water tool from TVB but get the same result maybe even better who knows, works for me.
Cheers, medical mark
