Welcome to the Halo Nation! I was a 1-3/4 PAD Marlboro Smooth choker myself, and I also found the transition really easy.... while I didn't "start" with Halo, I started with another popular supplier that used 808d style equipment... (I'm ashamed to admit that at first, I avoided Halo, just because everyone raved about them. I've kind of always been that way. I didn't see the original Batman when it first came out in theatres because of all the hype (tells you kinda how old I am huh?), but when I finally saw it, it was great. So yeah.... you'd have thought I might have learned...)
Anyhoo, back to the awesome that is Halo... I'm one of those folks that DaveOno was talking about... I've gone the gamut of various 510 threaded devices and clearos, only to find that aside from my trusty REO, (which is nigh unkillable!) I find myself using my old VV 808D batteries and Triton tanks. Flavor is just top notch outta these things.
I'd also have to agree about the VV Triton, and waiting a bit, as your tastebuds will get back to normal soon, and then it will be that much more of a difference.
Stay strong, and Vape on!
