Little update: played 9 with the new shafts. While they are quite a step up on weight (somewhere around 15 gr heavier) comparing to what I have been playing they certainly do not feel heavy. I was actually a little concerned they would be too heavy. I am happy to report that weight is not an issue with these for me.
Impact on these are more thumpy and dense if that makes any sense comparing to the ns pros St m43 (I think these are very similar to ns pro gh950) I have been gaming. I quite like it. There was a Wilson demo day that day. I hit a few balls with their new blade which looks gorgeous by the way. They feel superb when middling it. But that doesn't happen often enough, so they are not for me 😂. But they had the standard dynamic golds in them. I actually feel the standard version is a bit smoother than the dg120 version. The DG120 feel a bit crisper overall to me. I actually prefer the standard version from a feel perspective. But I am so far not unhappy with the DG120. Obviously, need more time but it is a promising start.
