I wouldn't say fly sparging is additional work, I actually find it to be less work but more time.
The time during the fly sparge for me is a perfect time to get other things done such as measuring out my hops, clean up and or organize, drink a beer, solve the worlds problems, drink a beer, put my feet up and of course have a beer. Did I say that?
I would suggest brewing multiple times using different techniques to find out what you like the best before you commit to a certain build.
