I really hate to necropost like this, but I'm led to believe that this is the correct place to discuss the current CFG USB Loader Mod, after originally asking in the main CFG Loader thread.
I've been using cfg70r78.11 for a little while now with great results. I also use wiiflow-lite, but may need to shift away for the foreseeable future due to some suspected SD card corruption issues.
The only feature I've really noticed which cfg loader mod doesn't have, which would certainly enhance my experience, and remove dependence on other loaders, is integrated support for listing .ciso formatted GameCube games. These .ciso games, converted using "wit", work very nicely now in Nintendont (AFAIK it's the recommended way to compress/trim, since it preserves structure and internal offsets), and show up in other loaders, but not here.
Regardless, much appreciation for all the hard work!
