If you already have a functioning system with 3.1 ROMs, I wouldn't bother. My A3000 was still on 2.04 so I thought I'd make it as modern as my A2000 and A1000, so I went for the Cloanto 3.X... but my floppy drives wouldn't recognize any disks, so I had to roll back to 2.0 and wait to get some 3.1 chips instead.
