Hey grinders :)

I play nl100 and nl200 regular 6max cash games. I played more than one million hands with more than 50k in profits at this limits and lower so i´m not exactly a begginer player. Anyhow, i´m looking for a coach to improve my game and hopefully reach higher stakes. I´m not famialirized with many good coaches as i´ve been busy grinding the games :) So my question is, any recomendation about RIO coaches that best suits my games and skill level? Thank you.
