Well, I'll be 60 this year, and have thought of getting rid of my STS set, too! I did the full rotation when it came out, and that was quite a commitment from me! Since then, it has sat on my shelf.
I will say, I have never lifted anywhere close to what Cathe lifts. I'm an intermediate exerciser, but I like strength training workouts. I need to make the workouts work for me, if I'm going to purchase them, and then use them.
I have some Cathe workouts, I've never even done. But, back in the day, I'd get the whole shebang during the presale!
For myself, I'm not quick to get rid of workouts. I may come around again and try it, and be really thankful that I have it. Even if I have to reduce the poundage that is lifted, eliminate certain exercises, or reduce the time I workout.
The biggest problem for me is getting through all the workouts that I have. Can I do it in this lifetime? Maybe not.
My other problem is I just don't like hour long workouts anymore. Thankfully Cathe has premixes with most of her workouts, though some of those are longer than the original workout.
If it were me, I would pull it out and use it again. Ahem, yeah I should do that. Then, I'll know for myself.
I like Linda's idea of doing a week on/and a week off. Or, two weeks on, etc. You can shorten the rotation if you find you prefer one meso over another, too! And, add some of your favorite non-strength workouts on alternate days so you enjoy the process.
It also might be helpful if other VFers wanted to do the rotation with you? Maybe there will be some folks and a check-in can be started, if there is interest?
