That was my first thoughts too when I tried 2kNL.
Many respected posters here say that 2k is harder more aggressive etc. so I decided to stay at 1k for w while (a while = at least 60k and probably 100k hands).
Assuming I would move up to 2k (I have enough bankroll) and 4table full tables I would need a winrate slightly above 5PTBB/100 to match my hourly rate at 1k (6tabling 6max).
Now I know it wont be easy if at all doable + the games are more aggressive and swings are bigger. So I am not sure moving up is worth it (at least for me).

Best wishes
