Right size

How large should a Clan be? Is it best to have a clan just large enough to let any member have a chance to raid with experienced raiders whenever they want to raid, without having to take anyone from the tower, or friends of friends who have never made a orchestrated raid as a team? Spartan, one of the administrators, has stated about 20 something is the optimistic number, to which I would agree. Patmcgroin, another administrator has yet to state his opinion, but from what he has talked about, in conversations, I think he would agree Clans of hundreds might be too big.
