Looking to buy cross country spikes for the upcoming fall '11 season. I'm looking for a nice lightweight spike. I was looking at the nike zoom forever XC 3, but the spike only has 4 spikes. I want a spike that is good for indoors as well. I was looking at the nike Victories XC, Asics dirt dog 4, and adidas xcs 2. What are some other amazing xc spikes out there?
