Speaking for myself, I wish more fishermen would replace their vintage FG with Graphite ... and then sell these unfashionable and unwanted relics to the unenlightened few, myself included, for an inexpensive sum.
Personally, I have gradually replaced all but one of my graphite rods less than 8.5' with fiberglass. That one graphite I like to fish with is an 8' 5 weight Orvis full flex. It feels like fiberglass. I think it's rather telling that the graphite I like is prefered because it feels like fiberglass.
But anyway, when properly balanced, I find that the my 8.5' fiberglass is more comfortable to cast than my 8.5' graphite. I rarely use a 9' rod, but I have a graphite broomstick ready for stripers. However, I do like my LL Bean Double L 10' 6 weight for fishing streamers and nymphs in lakes and reservoirs. It's said to be a medium action, and once I get used to the length, it can cast some serious distance and yet still be easy on the arm.
