I agree with both sides. That's what makes our job so difficult. There is no clear cut answer on so many different things. They blended A1with A4 because one was more heat tolerant and one was more cold tolerant so over time no matter your climate the better suited grass would win. That being said, I wouldn't want l-93 mixed in with either because it's management style is so different like Patrick pointed out. I think that if your goal is to change to a denser variety over time there is some merit to interseeding, but besides that I haven't seen a great enough germination rate to justify the cost. Over time it will all mutate any way, so why bother.
