Just my ponderosa pine "test" logs...I have more pine than I could want to burn, and you can't even give it away nowadays...the bark beetle has been killing it, so there is a bunch of it. It doesn't make the best firewood anyway, but is good for getting a fire going or just a fire for the "shoulder" seasons.
Hardwood is a "tougher" test for a saw, but I need to go scrounge up another oak test log for the video area. That larger 24" round in the video was a good test for your saw IMO, it pulled pretty well through that and I wasn't having to baby it to keep the rpms up either. If you're mostly using it for a limber, you might even want to upgrade to an 8 pin sprocket for some more chain speed.
