Monotherapy min-maxxing?

For about a year and a half I have been on 5mg EV weekly and Spiro 25mg twice daily. Everybody's talking about monotherapy but I feel good on my dose and levels, averaging around 250 pg/ml E and 15 ng/dl T. Bloodwork on trough of course.

Should I just start monotherapy at this point? Like I have no real issues with the spiro and my bloodwork is stable. Do I min-max at this point or stick with old reliable?
