What's to prevent one of the incorporation mills from creating a flat fee syndication platform to manage the LLC and provide template documents? Asking for % carry as a platform that streamlines the legal filing and record keeping seems aggressive.
Comes down to dealflow. Quality angels are sought after, and if they're capable of syndicating a larger round, so much the better.
To quote PG from http://paulgraham.com/fr.html: "The best type of intro is from a well-known investor who has just invested in you. So when you get an investor to commit, ask them to introduce you to other investors they respect."
