FC100DL vs TSA120

Hi I'm new to AM
I have a fantastic FC100DL, 1st series (black focuser), first pieces sold which I am very happy with and which is superb as well as a pleasure to use. The diameter fever and the idea of "getting more" are driving me to sell the 100 mm and  to buy a TSA 120.

However, I begin to doubt that I'm doing the right thing. I also have a mewlon 180c and the idea is to sell them both for the TSA120. Do you think this step is silly of me? according to your diagnosis do I suffer from "instrumentitis"?

If aperture fever is the driving factor I would say keep what you have, 20mm is not a lot and you already have 180mm with the mewlon. Now if you were thinking a 150-160mm refractor that would be something to think about.
