I have XC Victory 5 spikes for this season, but at least half of my races will be on courses with 70% asphalt/hard pack dirt and gravel/boardwalks. I don't like putting the "blank" spikes and using them as flats. Would the streakflys be a good racing flat for those courses? Nike makes the waffle XC, which is my spike without the spikes (and the Rival) but I was wondering if the Streakfly would be better. I need to do well on those courses to stay in the top 7, and make the championship meets for my team. Most of the reviews say get the Next 2%, but those are way too much
