The fatwood pitch burns like plastic in my opinion. It does not require a lot of oxygen once ignited.
The reason the fatwood seemed to perform better too is that by the time I started using Super Cedars the screen was already quite clogged. It got worse with each passing fire.
Thanks guys for the sanity checks.
4 fires started now each with 1/4 puck. So far so good. The outside fire pit is calling me now too (bit of snow falling today, overnight freezing, lots of stuff to burn up) so I'll probably use one out there too just for fun.
