Velodrome - Track Gear, Tools, Saddles, Gloves etc.

If you're doing sprinting I'd recommend steel over aluminium even though they are 400g or so heavier. They are A LOT stiffer which means better power transfer and control. You're not going up any hills so the weight does not matter as much. Plus, 400g is only like 0.45% of your system weight (assuming you + bikes = 90kg).

I've heard about it before. Definitely won't get rid of my Steel ones.
