I don't ever plan to put a cart on mine either.
Now, the long drip tips at GP are all black............I want the colored ones. Is Avid the only place I can get them?

vape was set up at Philly Vapefest. They had cannon 306 drip tips in colors, I picked up purple, and won a green one in the raffle. I don't see them on their website, just the black and clear cannons. You might try to contact them directly to see if they have any left, they had red ones too. These are my favorite drip tips, the colors are transparent so you can see how much has been dripped.
