I made a post about it in the What Are You Watching Right Now thread. At least we get to actually see some of these chilis that he's been talking about.
There are flavor changes to be expected with each color, but it'll still have the general flavor of that pepper. I thought I disliked orange pods until I had Bahamian Goats. I also thought I preferred brown/chocolate peppers in general until I tried chocolate ghost and nearly puked.
The flavors aren't easily discernible for me either. It's a matter of texture. I love a good crunch and that UFO shape on a TFM provides it masterfully.
