I've tried a few now but the only one I use for Bat refurbs and my own bats is the 3M helicopter tape. As I said in a previous link its what Julian Millichamp uses so I reckon he knows his stuff in that area. Every bat I have fitted it to so far had no complaints and its probably better than it needs to be for protecting bats due to its tortion/tearing properties. It's not cheap but as they say you get what you pay for.
I usually trim about an inch off the edge and finish the toe with a drum/belt sander. Again I watched Julian do exactly the same when he was based down in Daylesford, Vic.
