One thing for sure, having done it, I would never terminate a clover plot again because I thot it needed it. Did that to one, leaving the other for another year, and the latter with a little work is still going strong after 10 years. The redo took couple years to get back up to speed.
Personally a clover / chicory mix is hard to beat. As you prob know as I've shown it multiple times on my thread, I do have a 6 yo clover/chicory plot that includes alfalfa . Been pleased with it with very little maintenance on my part. My assumption is it would last a few years and transition into a mainly clover plot. It has maintained itself well going thru a year long drought in 17 to record rain in 18.
As I've said multiple times, I would assume the alfalfa no longer existed except my exclusion cage proves otherwise, the deer just keeping it mowed short and hard to see. I mow foot+ high to control weeds and have never baled.
To answer your question tho, fav is a clover/chicory plot with fall overseed of WR and/or WW. Good luck.
