It's human nature to be curious. Sure I like what I have, but what if there's something I like better out there????? Besides the fact that even for the flavors I've found that I REALLY like I still find I need to change flavors several times a day so I do need a variety of different ones. I also need different flavors for days when my taste buds just don't want to work correctly.
With all that said, right now I'm at the point that I have found the 5 or 6 flavors that work for me daily so I'm stocking up on them and not ordering from other vendors now or trying lots of new flavors from the vendors I do order from. I've still got a lot of variety in a lot of small bottles of flavors that aren't my favorites and that I'll probably never order again but are still ok to use when I want something a bit different than my favorites. DIY is my next venture to play with a bit. It's a lot less expensive than the trial and error of buying new flavors from vendors so we'll see how that goes for a couple months.
BWB is the one vendor I've not ordered from that I would love to sample a couple of their flavors but so far I have resisted making that order. We'll see how long I can hold that resolve
