Milk bubbles up alot, once it gets in your hose, that's no good... Now It will start to rust. Nammor hoses are excellent, beware of fakes.
It looks like you have a coconara on there. Good choice if that is what youve got. For a vortex bow I would never use less than 2 coals. Usually I have 3 on the edges, and move them around as needed.
I would upgrade to the Bambino.
Theres a video I made about packing a vortex. This is by no means the RIGHT way to pack a bowl, everyone does it differently, but maybe this will help.
