Check your vacuum at idle. Your choppy idle vacuum might be in the range the springs normally vary things. If possible, get a long hose and check your vacuum during various aspects of a test drive. Those springs play a major role in adjusting mixture from WOT through cruise and knowing your vacuum through that range would help in selecting the proper springs.
