Is 5gm a good weight?
You’re right that there is a fairly wide tolerance for weight - 5gm out of spec is not unheard of and a 5gm spread (2.5 either way) is really pretty good. You’re also right that some manufacturers (Mizuno) will sort for weight, especially if they know that a certain head is going on graphite rather than steel or is going to be built under or overlength. They will also sort out specific heads for Tour players. Guys like Dana Upshaw who have a special relationship with Mizuno may be able to ask for specific tolerances, and any Wishon fitter can ask for handpicked heads from TWGT at a small upcharge.#N#However, any competent fitter can adapt heads to get smooth weight progression, even if they’re pretty far out of whack when they first get to him.
Is there a direct relationship between swing weight and shaft performance?
There is not actually a direct relationship between swing weight and the shaft performance (or flex). The flex or the performance of the shaft is really a function of the head weight, not the swing weight.

It doesnt really work like that jeremy. Shafts come in a flex based on the shaft alone, so every s300 is (almost) the same flex. What the rule of thumb that you are using is that if you load up the head so much that it changes the swing weight, this will cause the shaft to go softer.
What happens to the shaft flex of a golf club when the swingweight is lower than D1?
However, if the swingweight of the club is lower then D1, and then the shaft flex becomes progressively stiffer. Conversely, the higher the swingweight of the club over D1, then the more flexible the shaft becomes. This is only true if standard grip weights (50g +/- 5g) are being used. But shaft weight alone is not the only consideration as ...

Can shaft manufacturers dictate what length and swingweight the clubs are assembled to?

I am recovering from a TFCC tear in my wrist and I'm looking to switch my irons out from steel to graphite to help with the shock to my joints. Right now my irons have a D2 swing weight and the irons I want to go with are D0.
Feedback
Let's put this in perspective, 2 swing weights equates to about 4 grams, so not a lot. The other thing is swing weight is a crude standard for assessing club head feel. Depending on the balance point of graphite shaft you buy, there might be more weight required in the head, than your current irons, just to hit the D0 target.
Feedback
Davemac is spot on! The balance point of the shaft can affect the feel in ways the SW will never indicate. Have one built and test it by swinging it and hitting balls. If it doesn't feel EXACTLY how you want it to feel, have the fitter adjust it and continue until you have it perfect. Then build the rest of the set from that.
Feedback
Built a set of RIP irons, +1/2" and they still were like C8/C9 swingweight. I tried an ultralight grip and that got it to D0. I had to wrap lead tape around the hosel of the club to get it to D2. I like D4, I just gave up.
Feedback
If you are changing shaft weights...start from the beginning. Don't go into it with a target swingweight, as DM already suggested, start with a single iron at very light swingweight and add head weight till you find the sweet spot, you can then build the others to that spec.
