What Quints For Hecarim?

Hi guys, I've been playing a lot of Hybrid Tank Hecarim Lately but I'm still stuck on what runes should I use, if it doesn't bother you it would also be nice by giving so numbers thx <3 I usually go ap quints, ad reds, armor yellows, 2 ap blues and 7 mr blues. But I'm also considering going ms quints, ad reds (i might want to buy hybrid pen), scaling hp yellows (who doesnt like hp?)/armor, and scailing mr. Idk which to choose and I've done rlly well mid game with the ap quints. / / Also just wondering, while I use e, does Mobility boot's passive go away when I auto someone or the +115 movement speed stays until after the auto? I'm just a kid plox, help me, I'm dying of loneliness kappa.
