Well, to be honest, the mixture of negative and positive posts in this thread are pretty appropriate and indicative of the business. There are strong positives and negatives of both captive and indy.
Personally, I think that starting indy has too many risks, both for an agent and their clients. There's a great deal to learn, and trying to learn it all by trial and error is asking for trouble.

Personally, I think that its up the the individual. Some people learn better when messing up a bunch. Some couldn't deal with the "Kool-Aid". Its up to that individual i guess.
