If you're new to honing, I would definitely send it out (after a test shave) if it needed it. There have been so many full hollows marred and scarred by beginning honers that I simply wouldn't try on a new full hollow without some experience on a heavier grind and less valuable razor first.

If you're dead set on honing it yourself, my rule of thumb is that on a full hollow with a set bevel and not needing any correction, nothing coarser than 4k, so try the 8k or 12k first with super light pressure then strop and give it a shave.

Finding a honing mentor is probably the best thing that you can do for your razors!
