The best TFA flavors for 'single flavor vapes'

[nwasiq]

Just recently got into DIY and bought kiwi and blueberry flavors from a local shop. I vaped both (after steeping for sometime ofcourse) and it seems that both need something more. I've heard that TFA is the best for flavors and I was thinking of ordering 5-6 flavors at the same time. What would you recommend are the best flavors for single flavor vapes and would go well with each other if I decide to mix them?

Edit: Sorry, didn't know about the DIY sub-forum. Posting this question there
