1. I'm reading that the Berts/Cannon/Traxstech tracks are the same dimensions (interchangeable with said rod holders). Is this correct? 2. Are the quality (build, looks, strengths) of these said tracks similar? I'm looking to add a couple more 24" tracks and I seem to be able to find the Cannons at a better price (about $15 per less). I have only seen/used the Bert's in person.
