Absolutely agree with Star, stick to what suits you but let the rest enjoy whatever system suits them. My class is about half & half, so although there is some discussion on propoints, general exercise and weight loss topics are basically the same principles and we get as much support from one another as from the leader. You might find quite a few others are still on Discover if you ask around your group, although about half our group are on Discover, only 2 of us have actually said so out loud in the meeting.
