I've got the pink and orange. I agree, the pink is great and easy to work with at low or high flavors.
The orange I commented on here, with a few follow up's under the original comment
Tested 4% now and get a bit of flavor, like you'd get from straight orange or tang. oils, but nothing candy like and nothing like I get from the pink. It seems to me to be more like just a straight up orange oil flavor. Less than 4% I was getting no real detectable flavor, and I think if I go 6% or more it will only be more orange oil aspect, since I've let a 4% test steep for 4 weeks and still no real changes towards anything other than what's mentioned and linked above.
Pink Burst is great!! Getting ready to mix more of that one right now actually!
