Commuting FG has been underwhealming for me. Same basic riding as on my single speed or roadie, no coasting but I hardly ever coast on my ss. I have to think more about the stops and the steep downhills are annoying. i already spin fast and apparently have a good smooth stroke since many say the fg helped them and i just dont feel any difference.
I ride a lot and ride many different bikes so i appreciate it for what it is and for each different stryle. i'll keep it but dont feel why it has a big draw other than the fringe effect most adolescents and young adults are drawn to.
Riding bikes is fun and each different bike has its own purpose and personality so have fun with it.

If it revitalized your love of cycling then great!
