I’ve considered trying Vance, but having finished Tull I think it would feel strange to hear different voices for the characters. I didn’t choose a narrator consciously; I think Tull was just what I found on Audible.
I was pretty disappointed after purchasing Vance's Master and Commander because shortly thereafter, the Vance versions disappeared from Downpour. That's why I ended up with Tull's Post Captain. I did find CDs of the rest of the Vance series on Amazon, but ripping dozens of discs is tedious.
Understandable! I will say that, if the King’s yards aren’t providing what you need to continue your voyage, there’s already the option to go privateer. It’s not something I’ve really done, but there it is.
