You got it right, Vert (he does reenforce his trees) used to work in Luke Wilson's shop and then started his own company. It is very similar to Joe leaving Toro and starting ITZA. It happens all the time in the glass game as apprentices with standout skills quickly figure out that it makes fiscally more sense to start their own brand. Luckily the VX team of glassblowers come from scientific background so the only thing they are interested in are creating exquisitely crafted HydraTubes.
@vapormonkey - Properly designed percs usually add very minimal drag. If you like the diffusion of a certain perc and want more drag, you could always add additional water. Water tools with percs can be cleaned by using something like Grunge Off or Simple Green by soaking it over night and rinsing. An overnight soak will remove close to all the residue left behind by the vapor.
