I'm running it now. The stock guide tube helps manage the spool well enough even full. You just cannot get to the cartridge release clips. You have to remove the nut. I can live with that Maybe a quick-spinner?

I like the fact that the post is easily removable without loosing the nut. That would ruin an otherwise very portable system.
Place the hole for the post carefully if you want the nut to wedge into place when installing the post.
Or you can always make up a custom nut that meets your already cut hole of course

Enjoy Bob!

Oh, you can always print those custom flanges
