Have one of the new Humminbird Locator/GPS units, looking for ideas on whats the best GPS SD card to use on Lake of the Woods.

I run Navionics chips in my 'Birds and the Navionics Platinum is the best I've seen. That said, Lakemaster has recently introduced an Ontario map chip but I haven't had a chance to see it yet in action.
