Let it ride. Always let it ride unless you have made a gross error in the description. You will never be able to explain the relist to everyone's satisfaction (you won't even know who is watching and has not bid yet), and will scare off more bidders than you will gain by having an item specific checked.

Personally, I rely zero on item specifics, best matches and categories, and primarily use very specific searches. The less I can leave it up to eBay Rio show me what should be buying, the better.
