Tony,
So no till champion segregates, but planted in a traditional method, it doesn't? Does that make sense to you? The anti-champion crowd loves to spread the segregation stories, but I’d love to see some real documentation. Usually the segregation is more about contamination, and not getting a good kill on the old grass prior to planting.
And while contamination is a real problem with any of these grasses, its important for people to understand that is not a grass problem, it’s a supplier problem. Some farms keep their fields clean, and some don't. Suppliers that want clean grass will kill off an entire field if they get any sign of contamination, others worry more about the bottom line and spot treat, but once its there, it’s hard to get rid of. Clean Mini Verde is an excellent putting surface as is Champion and Tif Eagle. Most of the negative "stories" that get spread around have a lot more to do with human error then bad grass.
And you're right, Champion is the slowest of the three. I like that, other supers that like aggressive grasses probably prefer one of the other varieties.
