Yeah I agree.. I think the most widespread problem I have with vendors is that they seem to be lacking flavor.. they seem to just disappear after a while.
Everything I have tried from Goodlife vapor is good and strong. They have a wide selection so there is something for everyone. My favorite from them is deadly sin. I'm still not sick of it, and that's saying a lot. If you like sweets that is one to try.
Also, vapetrik is VERY strong on flavor. I am vaping dorky stud from them right now. I actually had to cut it down with a plain tobacco because it was too rich on its own for me. I used three parts liqua American blend and one part dorky and I still taste the dorky front and center. Plenty strong even with the dilution.
Mt Baker.. well... I haven't had good luck with them. I have their butterscotch with two flavor shots and it needs about five more. Alice in Vapeland too, I can't even taste them. If you want flavor, I wouldn't recommend them.
