that's really not the weak link I don't think. Don't be skeered, you'll be fine 
As for the sleeving it actually can make it WORSE depending on how it is done, all the stress is now concentrated to that one edge. If you do sleeve it make sure the edges of the sleeve are not cut straight (do them at a 45degree angle). I still don't think it is worth it..
I was just curious, doubt If I will do it. It looked kinda shabby, but i didnt know how good the idea was
