I've missed a lot, catching up here! As always I'm impressed,
@Vape Donkey 650, your gear.... I hope I have a collection like that at some point... Up until yesterday, I was using all of my v3's without WT, all the time.
I finally had the money to grab an adapter, hydratube, and extra v3 to try it out. I ordered the hydratube from Matt, and it is great quality. While it is not a $200 piece of glass.. that's not how much I paid, and I'm happy with it for the qualities it has. Like has been mentioned, it will sit on the base, but rocks a little bit. There are some noticeable welds but that is OK because the birdcage/matrix perc hits VERY evenly. I am very familiar with china glass and the uncertainty that comes with, so this was a perfect hydratube for me. I also have a d-021 as my dedicated rig (w/ ceramic nail) and the percs are very close in shape/size, diffusion, and function. This one sits completely under water since it is lower down, which I like over the d-021.
As for the v3 adapter, I gotta say, I disagree with the beta testers! I know everyone called for a shorter adapter than the betas, but I'd prefer one of those (if anyone isn't using one of the longer ones and wouldn't mind parting with it... let me know!). The reason? This one is JUST too short to use with my Tesla Stealth(s) - pictures soon! Since I was around last, the Mrs and I have added to the collection. She now has a black Stealth TC40/black v3 setup and a blue Stealth TC40/white v3 setup. I have three, a white/white, blue/black, and black/black. Each one serves its own function (currently one of three consistencies/ flavours etc) and thus they all get used. These are good since we use our v3's mostly for 1-2 hits of meds, so the smaller batteries don't kill us. They have become our go-to mods, at least for the most part.
Those who have seen the Tesla Stealth TC40s know that the fire button is (ergonomically) on the top of the unit. This is ideal for me, since a majority of my use is for arthritis pains in my elbows/hands, and I can use these devices even when I'm having trouble using my hands. Sometimes a front-fire button is no good for me, especially (the Mrs just likes these because now I can diagnose her vape probs for her, since they are familiar). Since the adapter is so short, it is very hard to fire our Teslas with the hydratube atop. Instead, I have tested by using it by heating to temp (unattached), then quickly attaching and taking a quick small hit. I take 2-3 of these as opposed to my usual 1-2, and am medicated about the same. This is OK, but I could benefit from somewhere between 2-4mm more space for my finger to fit between the mod and the hydratube. Then I'd be back to my familiar place for dosing my hits.
I've picked back up my vt75, as a result. Last night I finalized the curve for the medium donut. I am happy with it. It always stays in TC, though sometimes I need to unscrew and replace the v3 to get it to TC after sitting overnight (short lapses don't cause this). I am certain that this is because of the DNA75 chip's extreme sensitivity to stable resistances. When it cools completely, the vape freaks out. Starting over makes it happy. I liken it to the fact that you should power-cycle your smartphone at least once a week. I only use medium donuts/cups exclusively now, since they are leak-proof with two solid wires in the posts. I probably will not return to modification of the curve for the old large donuts, since I have 1 left that I do not even use and do not see being useful. Also, the higher TCR new large donuts are exclusive to my iStick, which I use for friends/family who are beginners to try out and learn the v3. So my vt75 setup is finally complete! It works amazingly with the hydratube. Set at 206C, it hovers between 198-204C while in use, and never spikes above 208C. You can get a cooler hit with a harder pull (198ish) and a warmer hit with a slow draw (204-206). I typically leave the temperature alone, set at 206C. The vt75, as I've mentioned before, and even now with the sometimes-needed manual reset, is no good for quick medicating. In fact, I need to medicate before using it, so I'm mostly using it for fun now. I'll add some photos tomorrow, and maybe some more comments on what I've noticed...
