Generally people go up in shaft weight as the club get shorter to maintain similar feel. It is not a hard rule but a general one.
It is not certain as said that if a shaft works for you in your driver it will be the best fit in fairway woods either. But it will probably work ok at worst.
I pay a 70 gram driver shaft and a 70 gram fairway wood shaft. It works just fine. I am considering going down to a 69 gram driver shaft as lighter seems to be the trend and it just takes a little less effort.
