I recently purchased a pair of the Elite 2's for my indoor and outdoor season. My question is how durable are the nonremovable titanium spikes? I don't want to run the first few meets in them only to have them ruined by indoor championship season, and then also outdoor. I have a pair of original dragonflys, would it be smart to run the early race seasons in the normal dragonflys and run more important championship races in the elites?
