JCinFla. Thanks

yeah, thats what I meant. can you send a picture of such one? Anyway, I dont have any other ones, I think I threw tips I had away, they werent very good.
I don't have any tanks that are for DTL vaping, nor the drip tips for them. Many people who DTL vape also often use an RDA or another RBA, too. Most of
them I've seen...have the much larger 810 drip tip, instead of the smaller 510 drip tip. The 810 is even much larger even at the very bottom, because the openings for them are much larger too, on RDAs and other RBAs for DTL.
But, if you even have a drip tip like the 1 shown on the left in my pic below...you
might be able to get a better DTL hit (though still not a true DTL hit) with your Zenith. That one is from my TopTank Mini tank. The one on the right
is the larger of the 2 that comes with the Zenith tanks. Both of them are 510 drip tips though.
The red line above them shows the actual width of the hole, all the way down to where the 510 bottom starts and the o-rings are. See how much narrower the hole width is on the Zenith drip tip? The hole at the very bottom
is the same size on each one though. it's also that same smaller size
in the Zenith tank lid (if you look down into where the drip tip goes). So, even
with a drip tip like the one on the left, you'll still be somewhat limited in the amount of vapor you can get through it in each DTL hit.
What is strange also is, using Ello Vate 0,15 ohm + iStick, im easily coughing after the hit. I have to lower down to 15 W (trying all holes open or partially open) to not cough. Maybe try with juice that has more VG. Any other tip? Maybe Id have better experience with 0,3...
With your Ello Vate, IMO it couldn't hurt to try the other things you mentioned: 1) eliquid that's higher in VG, to help cut down on the harsh hit and therefore your coughing, 2) trying a higher ohm coil, and/or 3) trying different temperatures. Many of us have to try several things to find the perfect vape
for us. You never know what'll work
for you, until you try different things to fine tune it.
ETA: Here's a link so you can go take a look at a comparison of 510 drip tips (used on MTL tanks, RTAs, etc.) and the larger 810 drip tips (used on most DTL tanks, RDAs, and other RBAs). You can see why an 810 DTL drip tip isn't going to fit in the drip tip hole on a MTL tank.
