I've been playing some more NL50 and I fail to really get my feet on the ground there. I am somehow running worse there. A lot of 'nut'-type hands I loose like set over set a couple of times. But besides that, I really play bad. Running really bad still makes me tilt. I make so many mistakes, and a lot of them for big pots. I get too aggressive against the wrong people and stuff like that. I'm really not satisfied with my play and am letting my feelings getting in the way too much.
Thats why I decided to go back to NL25 where I'm very confident by now. At least till I have $1750. Than I'll take another shot, but I will really analyse my plays that time. Only play two tables in the beginning, post hands and probably record everything so I can watch it back.
I'm making mistakes at NL25 too, but despite those mistakes I keep winning continiously.
Also the different betting sizes at NL50 still really give me trouble.
NL50:
7044 hands
-$286.63
-8.14bb/100

I also played more at NL25 and luckily that went sweet.
NL25:
last 6735 hands
$334.81
19.89bb/100

So back to NL25. Maybe I'll try playing six tables at a time. I usually play 2-4 tables.
I'll be dropping down to bronze soon 'cause my accounts aren't tracked. Of course I forgot to save the gold strategy articles on my computer :(.
