After years of not playing poker I am considering to start again playing 25NL as soon as it’s possible in my country. I will play 6 max no limit hold ‘em.

Unfortunately run it once decided to move on but perhaps i can still use it as a training facility.

Couple of questions,

Is it still normal to use a poker hud?
Is the rake still beatable at 25nl?
Is poker stars a bit good still? PS will come back in the summer rio is no option.
Are there some good videos or courses here to get me back on track again?
Is rake back still an important thing? Sure, money back is fun but i would choose a good site over rakeback all the time.
