I just realised that this thread is posted three times in three different areas of the forum. This coupled with demands for help, a reluctance to provide further information to those people who you are demanding help from, and a poor attitude towards people who are trying to help you and asking nothing in return is incredibly rude. You do not deserve the help that you are getting and I would not be surprised if you found yourself lacking in further help.

The real expert opinion is to assess what your needs are based on the type of riding you want to do with the bike, your build, and other considerations such as carrying panniers, aftermarket customizability etc. The real expert opinion is that a jump up or down on the rear derailleur spec makes way way way less difference to your experience with your bike than the fit, and the rear derailleur costs very little to change out (especially after selling the previous one). You are asking the opinions of people far more experienced and knowleadgeable than you and ignoring those opinions. There is a reason people ask these questions repeatedly and give this advice repeatedly.
