In return, I have about 15 mini protank 3s, I can send u like 4 drip tips if u want. I like those, but I also like the stock protank 2 tips. I see u are on Portugal tho, don't know anything about shipping little pieces of metal to Portugal. I have found that the only ones with holes small like we both seem to like are the little plastic ones, for sale @ many places. They look cheap, but I also HATE a large bore tip. Accidentally bought two HUGE bore tips & just gave them to a young cloud chaser at my local B & M. The tip with the aerotank mega is to me -- perfect. Might want to try that.
