Quick Update
I spoke with Mike on the phone today and he confirmed my samples are going out and should be here within 2-3 days, so I'll be doing some test batches on each sample he sends over and reporting back with my experience once they steep for 3-6 days.
Here's what I found out today. The conversation was short, not because of his time, but because I was actually on the road when he called so I didn't have a major list to ask. I asked the 3 main questions, but if anyone has any others, please feel free to let me know and I will see to it that I get them over to him. He's a friendly guy, so I'm sure he won't have a problem with it!
1). The flavors are concentrated and PG based. The concentrations they use are mixed with PG to provide a more fluid flavoring. If they were solvent-free (i.e. zero PG), they would be in an almost jelly-like form, which most DIY users wouldn't be able to mix properly. They are PG based for consistency as well. No VG options as VG is simply too thick for their flavorings and concentrations.
2). They do not buy from or resell for Flavor West; they are manufacturer direct. They brand and bottle their own and they also offer a co-packing option which means you can get your own bottles filled and labeled. This happens in a 1,400 sq ft facility.
3). Mike requested that if I, or anyone else have any issues, get in touch with them. This means if a flavor is too weak, too strong to mix, or if there's anything else that presents a problem, they will work to fix it. They have access to work with the manufacturer to modify the flavorings they offer. No many can honestly say they can do this.
4). Cleanliness is a huge concern for them and he assured me all mixing and prepping is done in an extremely clean environment free of any and all contaminants. I'm going to follow up and see if he can possibly provide some photos. I can't promise anything, but perhaps we can get at least 1-2 snapshots of what OneOnOne looks like.
That said, I'm looking forward to the samples arriving and to being able to test them. I threw a list at him and asked him to pick since he said they were busy moving over the weekend, so what I receive is going to be a little bit of a surprise

Again, if anyone has a question, let me know and I'll make sure it's included in our communication.
