Little late to the party I have been busy...

Back in the day that post was written and before the Reo and Vapage had hit the street, it was not uncommon for folks who used 100% VG or even high concentrations of (undiluted VG) to experience problems with their gear or pre-mature failures of their atties and cartos, and yes Isaac and I had exchanged at length on the subject. It can be said that although VG did not hamper performance in atties as it did in cartos, it did nonetheless.
VG doesn't volatilize at the same rate as PG, it is but an adequate carrier of our components, notwithstanding a God send to folks who are sensitive to PG, who otherwise would have had to return to the stinkies. (not a good thing) IMO VG (pure and undiluted) doesn't allow proper homogenization of our liquid's components, whereas we vape the flavour and nicotine components but only part of the carrier (VG). Back in the day of dripping (which seems to be a lost art these days) it was not uncommon to over drip, caused by the lack of flavour or vapour production in our vape, although the atty was sufficiently saturated. The atty was usually sluggish and the draw tighter at this stage. One would blow out the (what I termed) "spent" liquid and we would good to go again. Now about spent liquid.
Although I/we were vaping a relatively clear liquid, the spent liquid that was blown in a tissue was a med to dark brown residue (containing high carbons), which no longer volatilized. As can be seen when adding dark and high sugar content to this scenario, it exacerbates the problem exponentially because the coil becomes encrusted with these sugars and in turn your atty is now making caramel for lack of a better word.
IMHO although our equipment has improved somewhat, the basics haven't changed over the years. We still see hear folks disappointed with their cartos whether encased in a tank or not who insist on vaping Bobas Bounty with them. Sorry duh
your device simply ain't wicking fast enough for your vaping style.
It goes without saying that a lot of mis-information circulates the forums and gets repeated. The majority of which is unintentional e.g get rid of the top two (floating) wicks in your Protank. Why? Are you having wicking problems? or Were you having wicking problems? e.g dry hits? Customer no. Then why did you remove them (POed because now he has a gurgly and leaking PT). I saw it on YouTube or someone mentioned it on the forums.
In closing our equipment was built around PG liquids, although since those days manufacturers are taking into account that some folks vape high VG concentrations (not because of need) to produce "clouds of vapour". Their is a price to pay for those clouds of vapour, not just in equipment longevity but the reluctance of establishments to permit interior vaping because of the ensuing clouds (California). Heck we never produced clouds when we were smoking, so what is the fixation these days. That my daddy is stronger than your daddy?
As stated in the link I dilute all my VG by 20% with distilled water. When compared against my PG liquid folks would not know the difference with the exception that it is on the label. I mix at 70/30 and 30/70 and have not had any reported equipment failures that where attributed to the liquid. Even 100% VG flows like PG.
The aforementioned convo Isaac and I had in the day rel;ated to dripping and cartos. High VG concentrated liquids came to market from the US to prevent leaking caused by over dripping. As read here, the high concentration of VG was partly responsible for the problem, folks didn't believe it then and don't believe it now, but a fact nonetheless. This practice also led to premature failure of atomizers.
Where the proof is in the pudding is.... the invention of the drip shield
A great device for sure, used by over drippers. A properly dripped 901 doesn't require a drip shield. I will conceed that it is the hardest atty to drip on, but once mastered, you can successfully drip on any atty without problem. A 901 required 6 priming drops, fired for 2 seconds, add one more drop and vape 6 puffs. The 6th was a little on the weak side, add one more drop = good for 6 more draws = 1 cigarette. Smoke break now over, place in your pocket and when ready to vape again add a drop to the atty.
Bridgeless atomizers
leaked like seaves, why? You removed the greatest portion of the wick, flooding the cup and subsequently a leaky atty. Ya see the briged was designed to take the liquid from the cart and hold in suspension in the wick (SS mesh) the coil wick wicked the liquid from the main mesh to provide adequate vapourization at the coil, not a coil operating in a semi flooded or flooded state.
In my most humblest of opinions, it is indeed sad that folks only hear what they want to hear, vice what they need to hear, and then wonder why vets no longer post.
