Just some thoughts to share… Coming from a steel shaft at about 120 grams, moving to graphite is as much a weight decision as anything else. Graphite can range from 65 to 115 grams, and maybe even more extreme if desired. AreoTech SteelFiber has options at 65, 75, 85, 95, 105 and 115 I believe. I have found that moving from 120 grams to 75 grams was a real adjustment and I felt I didn’t feel the swing as well. For me, the 85 gram SteelFiber (R) was firm enough to feel like steel but at a lighter weight. It was the Goldilocks weight and shaft.
The other thing to consider is swing weight. Typically graphite will play 1/2 inch longer to maintain a normal feeling swing weight. So the adjustment in length and weight are to be considered. Not that this is a monumental decision, but it has some adjustment time built in.
I am not an expert in any of this but these are things I learned when transitioning.
