I usually like to have both charts, as each has their own charms.

I tend to 100.1% use the Bizer, and trust it for navigating (but always follow the markers on the lake as the last word). On a recent update to the Duncan chart, several people pointed out some errors in it, perhaps they have been fixed by now.

But my one complaint, Bizer seems to refuse to properly name my favorite rock! I guess they are trying to stay slightly PC, but I'm not sure why, it's well known on other charts by name, except on the Bizer where it is only known as FL "46".

Tell people that you are at FL 46 and they will most probably have to pull a chart to understand where you are located.

Tell them that you are at Nipple Rock and they will know exactly where you are without having to consult a chart.
