Five Day Master Class Series to Sounding Fantastic on the Cello

Hey there-
I am having my third Five Steps to Sounding Fantastic on the Cello Master Class Series in March and am ready to start advertising heavily. Is it ok to use the same name and promo but change the dates for this? I have done this one twice, and one thought is, people are tired of this and so show them something that looks different and shiny and new. The other thought is: stay with the exact same approach, the exact same picture and promo, as 100 people signed up each time. What do you think?
