Looks good mate. 320 is easily enough for a club bat imo, but I go further for my refurbs and new bats. However that's more for my personal preference and peace of mind, as most people aren't that bothered tbh on refurbs, as long as they're clean and tidy.
Hows the toe looking? If you haven't got clamps you could get some glue into the cracks and wrap tape tightly around, which should improve it. Then add a toe guard, shoe-goo or just linseed to protect it from moisture.
