I just realized that the shafts in my wedges are S200. I have always assumed they were S300 like my irons. Is that the typical shaft for wedges?

The difference between S200 and S300 is very slight and you shouldn't worry about it too much. The 200,s are slightly lighter than the 300,s by 3 grams, I would be more worried if I had found a middle iron with a different shaft. Most people have odd wedges which don't match the rest of their clubs. True Temper's spinner shaft is 124 grams, the same as your S200. Question, do your wood shafts all match? Again, most people carry different woods with different shafts. Check out golfclubshaftreview.com for shaft specs. Don't have sleepless nights about it.
This has to do with the problem that golf shaft makers don't have an industry standard for what is regular flex, stiff, etc.
Some clubfitters are starting to use the frequency cycle matching (FCM) scale for comparing shafts of different models and makes. The FCM metric gauges flex by determining cycles per minute a shaft vibrates when tested on a measuring scale. The higher the FCM rating, the stiffer the shaft. A shaft that vibrates 265 cycles per minute has a FCM = 6.5, which is fairly stiff. (To go from cycles per minute to FCM, you basically subtract 200 and convert the remainder into a decimal value).
Let's compare "regular" shafts.
TT Dynamic Gold R300 = 4.8 FCM
"Regular" ProjectX 5.0 = 5.5 FCM
KBS Tour Regular = 5.0 FCM
So, you have more than half a flex difference between R300 and PX 5.0 / This balances out somewhat on clubhead speed: the R300 is 12 grams heavier than the PX.
Harmonious, you hit the daily double!!! DG X100 and PX 6.0 both have FCM = 6.5 / For more details, check out chart below from the GolfWRX website.
