Re: A few maybe not so simple questions ?!?
1) AF more consistant than Layalina and nearly the same price.
2)Razan, and yes bigger hits.
3)Go phunnel. I use a ceramic on my Syrian because I can not buy a phunnel to fit that style stem.
4)I have not used Coconara so can't comment on them. I use Exoticas and they are ok. I also use Bilal Olive wood naturals when I want to use smaller portions without hosing a stick of Exoticas.
5)I don't use diffusers, no comment.
