If you are just now starting dripping, i think you will find why most "veterans" who strictly drip do so...
when i first started, i hated it... messy, needing to drip every few tokes etc, etc...
but after all the bottom feeders... cartos, etc...
there's nothing as consistent, and advantageous to a perfect vape.
I've found ways to make it pretty flawless, as most do. For me, I use pyrex, i use bottles with needle caps for pinpoint dripping... and i have 2 Provari's. I can't think of any other way (or PV) I'd rather vape.
Splashing? you must be using high PG ratio... i have never had splash, but i hardly go over 50% PG... the VG slows things down.
I have used both the reg. 306 dt's and the Pyrex...
from my observations, whether the juice drops down the middle of d/t to the bridge or down the sides of the d/t's the juice pools at the base of bridge (unless i take the d/t off, and drip around the sides of the bridge ... one drop on bridge, one on each side, and into hole)... but doesn't really leak... (those reg. 306 d/t's are tight - so tight that they can melt on to the atty cylinder if i don't take it off to cool a bit every now and then).
Even the Pyrex 306 d/t, a mother of a big, thick unit... like a lamp glass lol... has not leaked which surprised me since they are a bit irregular, hand made (blown?) glass.
Just started dripping for flavor testing, it's been an interesting couple of days, but educational.
I'm using the Joye LR 306 from GP's and both long and short Delrin drip tips. Cleaned primer with diet coke quickly followed by a distilled water rinse, blow and short dry burn.
I was IMO forced to debridge the atty as when dripped on, the juice just splashes off of it, not catching/soaking it up....resulting in it just leaking out between the DT and the atty shell (although none leaked out the batt hole).
Final results, I like dripping on these for the hands on and flavor testing.
RE: the Pyrex DT at TheEcig.com -- wow on the price. Realizing they're the only game in town currently for these and quite inventive and I much appreciate them filling the demand for them, and the fact they're handblown, but just sayin', not sure I can commit for that. Dripping is not yet my main vape form factor....yet.
