Stronger input & output shafts?

I was wondering if anyone knew of any shops/companies that make stronger input & output shafts... I know both are weak spots in the stock tranny... yet I have yet to see a gear set that comes with BOTH upgraded... For example, the Os Giken Close Gear Set comes w/ a strengthened input shaft, which is good, but from what I've read, the output shaft is the weakest point (https://www.rx7club.com/3rd-generation-specific-1993-2002-16/fd-transmision-strenth-254035/)...

I've also read you can cryotreat 'em...but again, I'm curious if anyone makes better ones to begin w/.

Thanks
