I noticed on VORTECH website that they have 8 rib pulleys and then they have 8 rib High Traction pulley's is there a diffrence in the pulley types because I cant tell in the picture or description what makes the high traction pulleys diffrent?

If I remember correctly, the high traction have lateral grooves in them. They work pretty good.
