I love switching up compounds during a long blast session. From tes/deca to tes/deca/tren to tes/tren is my fav. Then back to " maint." doses for a while then blast away again. It's just that you need to know how long at what doses and what combinations will render what type of results. But if you don't experiment then you will never know. Of course I'm old and on hrt anyways so the long blasts aren't a problem for me or for you if you really don't mind going on hrt full time.
