Gelesto is right as well. Visors are high in lamia right now though.

For CRP, leveling was easy as I swiped all the housing goods before patch so prices didn't skyrocket yet. Bloody Lance heads were cheap as well so grab those up and go at it. For profit, look for cheap "manor" items. I desynthed the stools which were going for 10k a piece and sold the wax which was going for 85k a piece. So far 1/2 chance you'll get it so that's a plus.

Militia spinning wheel was next for me as I was able to gather spruce lumber pretty easily and cost wasn't too high. past that you just have to hope for lancer weapons and bard weapons to drop in dungeons.

Just found out though that most GC greens are desynthable as well so that's my next stop
