I've been is somewhat of the same situation. I run 400s and I???m 5'10" and around 160lbs. It sounds like I run the same as you do. Not all with strength but lots of power, quickness, and flexibility. I ran in the JSCs last year and thought I did well. I loved the way the felt. I???m only a junior in high school so I don???t have much experience with spikes and don???t know what type I should be wearing. Sometimes I wish I could just use Nike???s facilities to find out how I plant my foot and whatnot and have them tell me what I need! That???s not going to happen though unless I become incredibly fast in the future. Anyway, I think I???m going from the JSCs to the Celars 2 this season. They have a bit of a stiffer plate, which should increase your toe off power. Check out my post 200m/400m spikes. 400Stud was explaining to me about the Celars and he will have a pair shortly and update on how they feel.
