Hello, I will be running the 400, 4x4, 800, 4x8, and 1600 this year and I am going to buy 2 spikes, one for the 4 and one for the 8/16. I was wondering which two spikes would be the best to get. I normally use the victories for the 800 and reall like em but I heard there's better spikes for the 400. I appreciate your answers. Thanks!
