With regard to large groups, the practical reality of my Mon-Fri bondage, errm, work life is that I perceive no major difference in availability between my current 1/14th and my previous 1/3rd! So I agree with Genghis; a significant number of large group members hardly fly!!
Nice things about big groups: Social. Well organised. Strong personalities don't dominate. Well maintained aircraft. Few or no cash calls. Cheap.
Nice things about small groups: Real sense of aircraft ownership. Much more flexibility for weekends or weeks away.
Just read the inverse for the bad points!
The really really nice thing about large groups is that because of the lower capital outlay and monthlies, you can buy into more than one share to experience different types without breaking the bank
