What's sop? Keriyah is what most people do AFAIK, "hayu korim, umishtachavim, umodim venoflim Al peneihem "
So I go on my knees, then bend over as most then this year I fully stretched out my entire body.
I use the Koren sacks machzor in a chabad shull, I'm always behind, I alternate between Hebrew and English. We finished about 8pm.
I seriously was not prepared at all. Just getting into that mindframe. To really say the Cohen gadols viduy and feel it, yom kippur is the zenith of collective and personal supplication.
I pray for me, for my community, the nation of Israel for all man kind.
I'd need a few more months to be ready! And we (chabad) use a very shortened piyut version. If we said all, I'd need 6 months just to be ready and a few days to pray it all.
