whole wheat formulas

Toast
Hello, I am looking for a 100 percent, whole wheat, sourdough formula that involves only flour, water, culture & salt. I realize there are many on this site and I would like to know what folks think is the best option. I'll be baking around 15 loaves in a convection oven for my CSB.

I use TXFarmer's 36 hour baguette formula, at 95% hydration (400 g water, 425 g flour, 150 g 100% starter). It has been a reliable formula for me, despite my slowly improving shaping skills.
