FinalAsgard I don't think that it will make very much difference what version to use for memorisation so long as you have a main version. If you wish to use CSB for some sections I think you can if you want to.
Another good place for audio bibles is Biblestudytools.com. It has many different Bible versions. It's free but you need to be online to listen if using the website. There is also an app version from which you can (I think-haven't done this) download audio bibles to listen to them offline
