OLogo Design Contest

We are a curling product manufacturer, we make shoes, grippers, brooms, etc for the sport of curling. Target audience is everyone.

black/white/grey

The attached logo is our existing logo that we will be keeping. Our existing logo uses a curling rock as the big "O" to incorporate our sport into it. We are looking for a design to go with our existing logo that will act as a symbol for our brand. We want it to incorporate an "O" to represent Olson, and we also would like to have something from our sport represented in it as well, it can be the rock that is currently used, or we are open to other ideas. We want a "symbol" such as how Nike has the Swoosh, or Sketchers has the S, etc... something we can use to identify our brand in a simple symbol on curling shoes, curling pants, curling brooms, and packaging, etc.
