Will I lose ability to achieve super orgasm on command by switching to Progasm from Progasm Jr.?

So just thought I would share my journey. I have owned a Progasm jr for over a year and a half now and I have finally made huge progress in my journey. Within 10 minutes of insertion I can usually always achieve a mind blowing full body super orgasm. I believe good things come to those who are patient and wait and I believe I enjoy my orgasms so much more now because I worked and tried to refine my technique until I have gained the confidence that I know from the moment I insert my Progasm jr my body is yearning to cum. Today I had a orgasm that lasted for 20 minutes straight, it was like a roller coaster of pleasure. My question is I saw the Halloween sale for the Progasm and I am thinking about buying one. What I'm worried about though is if I switch to the jr to the Progasm will it be like starting over or will it only enhance my ability to orgssm? What I don't want to do is lose what i have gained with the jr, but I'm also really intrigued what the bigger size will feel like. Is the Progasm the next model I should try if I want bigger orgasms or will another model be better? Also I reccomend the position of cow girl. Just grind your butt like you're a girl riding and it feels amazing. Thanks!
