I'm still building my tool kit. I don't have/carry a chain whip. Some carry a hyper cracker (or similar) or a chain whip and a lock ring remover to access drive side spokes that have broken, bent, etc. I need to invest in a Fiber fix emergency spoke and spare spokes.
I have a 29er, so I'll be off road at times. Make sure wheels (which were hand built) are properly tensioned before parting. In the event of a broken spoke, use the Fiber fix and replace spoke at camp.
