I recently got a new hurley, the stick used to play hurling. It arrived with a plain ash handle so I decided to add some grip tape. This makes the grip a little bigger around and a lot easier for some folks to hang on to. Especially when the hurley gets wet.
If you are curious about the sport itself there is a lot of information on the web. Just Google "hurling". You can start here at the wiki page.
Step 1: The grip tape
I decided to just use tennis racket grip tape. It's not quite as durable as actual hurling grip tape but tennis racket grip tape is comfortable, available and even if it lasts half as long, cheaper than an international order for the real deal. As far as I can see it's pretty similar but I'm by no means a regular or avid player.
So, just go with whichever brand you like. I chose Wilson grip tape and got Gamma over wrap I didn't end up needing.
