What pros and cons are their for flybarless and flybar heads. I've also read about flybarless electronic stabilization systems do you need them and what do they do.
Without the flybar, the rotor head is inherently unstable. The flybarless systems have gyros on all 3 axes to do the stabilization. It's just one more thing to go wrong: if one of the gyros on a flybarless system fails in flight, you're pretty much screwed. Also, flybarless systems drive up the cost considerably at this point.

The biggest advantage to flybarless is reduction of drag from the elimination of the flybar and paddles, providing more power.

Experience is something you gain only after you need it.
I wouldn't mind social media so much if it didn't involve people.
