I ended up getting some IRC Serac tubeless tires at a great price from Cambria Bikes. I rode them today on a short ride on mostly flat trails with a couple of moderate climbs. Conditions were mostly dry but a lot of leaves down over roots. They felt much more secure than my Pythons. I rode faster and felt much more confident. I could feel them biting into the corners and when they did slip a bit a couple of times, they took hold again quickly. No crashes today! I hope to take them out on some more technical trails tomorrow or Monday. I'm psyched to ride some more. what a difference to have tires that better match the conditions in which I ride.

Thanks to everyone for their suggestions.
