It's up to the Committee to decide, in advance, and publish for the competitors, what the rules are around handicaps. What any of us thinks is "right" should be overruled by the specific rules of the competition. Now if I'm on that Committee, I would want to use the handicap as of the date of the match, but I'm not the one making the decisions.
Thanks for that info. I recently injured my left knee (I'm a righty) and tried to continue playing with a brace on and then added a cortisone shot. I finally wound up with gel injection which does help with pain relief except that my brain doesn't want to fully shift weight back ro the left side. The injury is not structural, it was a re-injury of a 6 year old meniscus tear that I had 2 months of intense PT on and had not been a concern since until post-Covid return to play. My golf swing stops without releasing my body because of weakness and lack of stability. So I tried a foot flare on my left side, between 35-40 degrees. A much smaller flare on right foot, and I opened my shoulders a bit to accommodate. In practice swings without a ball it feels much better and I can swing through. Does that sound right? I will try it at the range because I am stumped getting "through" the ball otherwise.
Go back and look at Golf Digests Hot List from 5-7 years ago online and find the game improvement category. The Hot List is a bit of a joke I realize but you will see the offerings from all the big companies for that year. Then just go on Ebay and see what you can find putting in whichever club looks good. Ping, Callaway, Taylormade, Cobra, Cleveland, all good options.
Few different things to look at here. First as already mentioned 6.5K spin is really high and no shaft is going to bring that down by itself. I would like to see that number under 3000. I would suggest taking a look at where you are making contact on the face of the club as that can greatly influence the spin numbers. Also just fyi, that head is going to produce more spin than something from the last 4 or 5 years. I would almost be tempted to say find a new driver and just go with the shaft that comes with it.
What loft is on the current driver as that will also play a big role in spin and launch? Also did not see any mention of ball flight height. Assuming its really high, but wanted to check if it starts high or rises up after launch.
If you want comp shaft recommendations to the Slay, which is technically mid price range by todays pricing, there are tons out there. VA actually calls this shaft a high launch, low spin design. Now technically that isn't really possible as launch and spin go together ie high/high or low/low. It really looks more like a mid launch and spin design to me. Similar options to look at could be Aldila Tour Blue 55g (Ebay around $60), any Mitsubishi Blue board style (will say blue in name or have blue color on it) again in 55g (Ebay around $80-$200 depending on model) would be too options. What else did you hit during the fitting, as that could help narrow down options.
Last thing, I might watch this video below I did concerning finding the ideal set up for your driver. Again the swing is going to be the biggest influence but impact position on the face will also play a large role.
I golfed today. I golfed with some of my regular golf buddies. I almost backed out, but am happy I did not. Was feeling kind of down after last weekend when I SUCKED. Today was a much better experience. I did win the front nine, but am not sure yet on the back nine. After I totaled up my score I am happy. My friend Larry asked me 'Where were you last week?". I answered, "I have no idea". Golf... stupid game
