You are the start of a very long journey unless you really take some time to work it out now, swing speed has NOTHING to do with what shaft you need in a driver. As a very broad brush
transition relates to weight
release relates to overall flex
Tempo also plays a roll, some are very sensitive to flex, some aren't. Example, a long wallowy swing with an early release and slowish tempo,and the same swing speed as a fast hitter with fast transition and late release, may need totally different shafts. One a butt soft stiff tip reg flex at 55g and the other 95g butt stiff tip soft in XX. You really need to see a very good pro who can work through these things.
The above example is real btw, I swing at 110mph and use the 95g, my mate a guy at 125mph when he wants to be uses a much sifter and much lighter shaft.
If you really dont have the time just grab two demo clubs poles apart in flex and specs and have a go
