Personally, I have not found FF to be of a whole lot of use, and I've been using it a lot lately on long cross country flights. Really, so far, the only thing I've gotten out of it is being more comfortable working with ATC. Every time I've needed something, they've not been able to help, and they pretty much have made me route around any airspace just as I would have had to without them. As a VFR pilot, it's still pretty much up to you to navigate and avoid weather and traffic. Every advisory I've ever gotten I already knew about before they gave it to me. I use it anyway on long flights, but I often wonder why (when I'm flying into podunk airports). I do have to admit it was useful to have been in the system as I approached and landed at Addison last month. In crazy airspace it's worth it.
I do recommend the OP use it on this flight, and continue to on long flights until you understand it well and are comfortable with it. Then you can decide for yourself.
