So I'm a distance runner, 1600m/3200m guy, and I was wondering what kind of spikes to put in my "Nike Zoom Victories"? Some of my friends use pyramid spikes, while others have needle spikes. Then there is the issue of the length. Should I use 1/4 or 1/8 or 3/8? I know everyone has their own preference but which are the best for 1600m and 3200m?
