I'd say if you like the variety you have, all you need to do to revive the plot is to abuse the hell out of it. Basically, a strawberry plant loses vigor with age, even though they are perennials. To combat plant fatigue, go in and rip out half of your strawberry plants every year to establish a sort of continued renewal of the plot.
BTW, I've never had success with everbearing when it comes to size. I get a lot of berries about the size of my thumbnail. I left that plot to die this year and will be reconsidering what I want to do about fresh strawberries. I absolutely dislike most store-bought strawberries, agave sweetener helps...but still.
