Difference between DG 120 S300 & S400

[swpunchguy]

Anyone know the difference between the new DG 120 S300 and S400. I know the old regular version of the DG's were a matter of weight tollerances  but the new 120's have the same exact weight of 118 grams. I'm trying to decide between the two for a new set of Mizuno JPX 919 tour's or possibly forged. Is one slightly stiffer than the other? slightly stiffer tip maybe. I have heard the 120 S300 play slightly softer than the regular S300's so maybe going to the S400 120 would be better. Any feedback would be great thanks.

Someone might have to help on this. From what I understand the S400 was the tour issue initial offering for this shaft. Also had an X100 flex. Then later came the standard R300, S300, and X100. Now I have no idea what or if there is any difference between these two X100 versions. If it's like the 130g version then maybe the S400 just has the same tighter tolerances as the Tour Issue DG130. Again doing some guessing here. According to TT, if you played the 130 S400, the 120 S400 is comparable.

Thanks for the input. I used the standard S300 for 20 yrs but with the old sensicores. I have heard the new DG 120 S300 are the same but play a smidge softer so I figured maybe go the S400 route. From what I can gather, the 120 S300 and 400 are identical but if it’s true that they are and the only Diff is tighter weight tolerance then I might as well do the 120 S400?. Also to note, the fitter can put Sensicore inserts into the 120’s to make it a 122g shaft which might be heaven for me.

The S400 will be slightly more stiff than the S300.

Far as I know...the S400 is only available in a tapered tip.

Thanks fellow golfers. I will be pairing the 120 s400 with either the Mizzy Tours or the forged. Or a combo of the two. Thanks

One more note on this. I have been told by a few fellas that have the new DG 120 S300 that it plays a smidge softer than the original DG S300 so they suggest Hard stepping the 120 S300 once to match the performance of the original. MY question would be, wouldn't just going the DG120 S400 route do the same thing? to match the performance of the original S300? A golfer could go nuts trying to figure this out..

The only difference is really weight and tolerances. Ive been using the same set of DG S400's in my irons for over 10 years. Being that these shafts are weight sorted, if you get S200 or S400s you really like through the set, keep them forever. Theres a chance your new set could play completely different.

completely understand that since I had the DG S300 W/Sensicore in my old irons which i also loved, Mizuno T zoid pro's. However they are 20 yrs old now and it's time to move on and I'm not getting any stronger so The new DG 120 makes sense. That being said, the New DG 120 S300 and S400 are the exact same weight 118g, which is my dilema. In my warped Golf mind I think the best way to replicate my old shafts is to put sensicore inserts into the new DG 120 S400 or S300 and make them 122g with the same feel as before and a touch lighter.

I lost about a 1/2 club when switching DG S300, but improved dispersion. 
thoughts on an option to regain that distance with a lighter shaft option?
