Razz is my favorite game. I recommend play 2 tables max. I love razz.
First 20 Sit-go of razz I've played I won 14, 2 second place and 2 third place. In old days have Sit-go of razz at pokestars, but now not anymore.
I agree with @badgerer concerns about MTT's. In begging best play is conservative. Don't waste chips with crazy guys. They not goes too long and maybe spoils your game in beggining. 20 Buy-ins is enough I think.
I've played too much cash medium stakes. Have big differences between stakes at cash games. I don't recommend micro stakes of ring games. But you will need find your stake.
For medium stakes $2/$4 and $3/$6 I enter with $40 / $60 at ring games. Is good enough.
MTT's I recommend beat micro and when confortable move up slowly. MTT's low+ have good players of razz.
But I'm out of razz years ago. Good luck in your journey.
Regards
