Love the GoldStars, both the original ones just before they dicontinued them, and the revisited/reissued ones.
If they worked, the 435s will be too lite; the 875 is slightly stiffer. My DD was in GoldStars at the same jump level: strong stroking, long legs, powerful knee bend. Went to the 875s when they discontinued the GoldStars initially.
They did revamp the Gold Stars from what you remember: they'll be a bit lighter, and, I believe, a bit lower cut on the ankle.
