Yeah,tfa honey is a rough one.I've only used it a couple times,and had no luck either,even at .5% it was very strong and not so honey tasting haha.As for flavors to stay away from,that's tough to answer since taste is so subjective.M-type is the perfect example of that.I think it is absolutely the most horrid thing i have ever tasted even at 2%,but there are several people here on the forum that use it and love it at 10% or more.Honeydew is another that i find nasty at any %,but see alot of people using it everywhere from 2% up to like 15%,i just can't do it haha.
By the way,that PB Cloudz sounds pretty good,i'll give it a try this weekend.Both of current adv have peanut butter in them,so this one sounds perfect.
