New quest bars...

First, thanks for the samples.
You have definitely made improvements in how you do the corn fiber based bars. In particular, I'd say the texture is now better than even the original bars. The original bars had a rather gooey and stickiness to them - I would always make sure to eat them in wrapper because of that. These bars seem far better to touch, and the mouth-feel on them is better for it.
As far as pure taste, you've definitely improved from the initial use of corn fiber bars. Originally, there was a lot more of an after taste with them that was a bit sicky-sweet and metallic. Most of this is gone now. The direct sweetness isn't exactly the same as the original isomalto-oligosaccharide based bars, but that isn't entirely a bad thing for me as the consumer. The isomalto-oligosaccharides tended to cause a strong craving, similar to the saltiness of potato chips causing the can't eat just one sensation, but for the original Quest Bars, this was a kind of sweetness. I find the new bars strike a balance where I get a candy bar-ish taste but I'm not reactionarily looking to down another one. I hope the removing that quality doesn't hurt your sales, as I do appreciate that difference as a consumer.
I also want to mention that last week I bought on my own a S'mores flavor. I'll admit that I did not like the S'mores flavor originally as it seemed excessively dry. I'm not sure how much you've worked on that once since it was corn fiber from the beginning, but it definitely has improved too. I'll definitely add it my list of flavors I like.
