What is a typical club fee? And what do people get for it? Only the organized rides or some other benefits?
No drop rides strike me as necessarily being an undemanding 'social rides' on some ability level, where the point is to stay together, where most participants can't expect to ride anywhere near their abilities most of the time.
Anytime people want to group ride to improve their riding ability, fitness, it should be unorganized, everybody is a free meat. Riders then separate into groups of their abilities quite naturally. It can be a norm that you get rides where it is expected the group will separate into two or three groups at some point quite regularly after the initial warm up. If that is expected, then no one feels bad about it. And if someone gets dropped all by himself, he has to join some group with lower abilities. Free market approach works much better than being too organized, you have much less bad blood, arguing and 'political' discussions.
