Word on the courts has been that Yonex was pretty much the only brand from which you can pick up sticks off the shelf and they'd be very close to spec. Meaning also one would not have to worry about matching between them.
I was looking at the Percept 97H, as that's pretty much the only heavy racquet on the market since the RF97A had left the show. Measured a few and was surprised and disappointed to find all of then a few grams too light and a few mm too head heavy. Sure you can get close to the 330 / 310 spec again with a slightly heavier grip, but then the fiddling around begins again...
Demoing a few other pre-selected sticks, I did like the VCORE 98 and felt drawn back to it. Although even at low tension I could feel pain in and along the whole arm, which has happened close to never in >40 years of playing at least hundreds of racquets. So not sure what's going on and why a good part of the energy needs to go in that direction...
Anyways, back to spec - in a store that only had 2 VCORE 98s, there was already a 6 (!) gram diff between them.
Struggling still and again to find an online retailer in Europe that would find me at least 3 matching sticks, I ended up ordering 6 myself, in the hope that 3 would be closer to spec and each other.
Turned out weight and balance were pretty close between all of them, however with 1 outlier each in weight and balance, respectively. 1 more frame that seemed close to the remaining 3 did feel a bit heavier to move around (3384900 below), despite just maybe 1 mm more head heavy balance:
(Still can't measure swingweight at home, so trying to at least develop a feel for it - thinking since only feeling a diff later on court as well would be a problem....)
Also worth noting that without the ~2g plastic wrap around the handle, 5/6 racquets were moving from the 305g VCORE 98 spec towards 300 grams, which at least in terms of weight is the VCORE 100 spec...
I do wonder a bit, why as a manufacturer, one wouldn't just put thin weight strips under the grip, to make final tweaks to get the racquets to fit.
Bottom line:
I think for players who care, one currently can not (no longer?) just go and buy Yonex off the shelf and expect true to spec material.
(I feel somewhat comfortable making that claim as at max, 1 of the 10+ racquets I measured recently seemed true to spec, and most others were quite far off. Maybe Y has fallen victim to its own success, in that regard?)
Based on my limited samples, I'd say one would have to roughly double-purchase, to then possibly end up with half the racquets to one's liking.
However as in my VCORE batch, one would still have to tinker around with the grip and / or handle - if one wanted to get to the spec that the racquets where developed and are advertised for.
Still not there in 2024!
P.S.: FWIW, the cardboard and rubber bands holding it that come on Yonex racquets seem to weigh ~14 grams. So with the ~2g plastic wrap around the handle, what you pick up in the store weighs about as much as a strung VCORE 98. Though obviously, compared to a string job, with that weight distributed. String would add an extra ~2g in the head (~16g total), and removing the wrap would take ~2g off the handle. In other words, you'd have ~4g more in the head, affecting balance and swingweight.
