OMG! I've been doing the same thing for daayyss. It really is nerve-wracking. This is pretty much SOP for me.I swear, y'all. I am so damn compulsive, I get on my own nerves sometimes.
This is the way it always goes. Get a new shiny thing. Don't matter what it is - mod or atty or drip tip - and then my mind starts just rolling things around. That would do better on that other rig, try it, no, it' doesn't, but it might do better on THAT one. Oh but then the sizes don't match up or I've got two of the same style mods with two different types of atty on them, and one is the wrong color or the drip tip doesn't go, or some damn picky-ass thing.
In the last several weeks I've gotten a second iJoy Shogun Univ mod from Wetvapes, an Imp RDA from Vaperz Cloud, a Recoil Rebel from @gadget!, and a 22mm Flave RDTA from @jcash74. Y'all would not believe the number of different combinations of pieces that I have tried since then, and not just involving these four pieces of gear. I will keep messing with all my active rigs for about two weeks (that's how it usually goes) until I have combinations that I don't think can get any better, or it may lead to me buying something else that is just the "perfect" piece to make everything go together like it should.
I bought a rose gold Goon to go on a copper Admiral tube clone, and the color and finish just isn't right. It has about worried me to death. I'd rather have a stainless RDA on the copper tube than to have a rose gold or copper RDA that is just a tad "off." So the Goon is now on a Tesla Punk Nano regulated tube (color isn't exactly right there, either, but I rarely use this piece), the Recoil Rebel is on the Admiral, the Mjolnir is on my stainless Vindicator where the Rebel used to be, and the Flave RDTA is on the Cold Steel where the Mjolnir used to be.
See what I mean? Christ, I drive myself crazy. But in the process of doing that, I have discovered that it's gonna be hard to beat this Rebel on the Admiral clone tube. Those two pieces vape like they were made for each other.
The amount of time it takes just for these decisions severely cuts into my day. I hope you find your perfect match. Sell the others to finance those new purchases. Lord knows I will!
