Ah success!!!! Ok, here's what's working for me (at the moment.)
Mya Bambino, Tangiers small phunnel, Starbuzz Marlette, 4 CH natural coals on the outer edge with spacer in the middle. I packed the bowl as loose as possible, just up to the inside rim. BUT, I packed down the edges a little bit to give some extra space so the shisha doesn't burn, and I used 3 rows of holes in the foil with fewer holes the closer I worked in towards the center. Working great so far. Not harsh at all, loads of thick smoke. Thanks for all the replies, I'll be using this setup from now on. Cheers!!!!!!
Here are some pics.
