Positional stats would help more I'd say... But from this:
You were playing a winning 22/18 style on NL25. Then moved up to NL50 and played some weird 35/28??? If you're not comfortable playing that LAGgy, I suggest you either try that out at NL25 first, or just play your normal game at NL50 as well (that's what I'd recommend). You were winning at NL25, you can easily be a winner at NL50 as well.
Also, it seems like you are 3betting quite a lot, and also calling lots of 3 bets at NL50. In my experience, guys who do this often get raped (by me for example, lol)... Reason is this: You probably get into too many marginal 3 bet spots, OOP or not, with dominated hands, where you should just be folding preflop. The play on NL50 is not THAT aggressive, that you have to defend a lot...
Fwiw my own stats on NL50 concerning 3betting are something along the lines of: 3bet: 5%; fold to 3bet: 75%.
You don't need to be that overly aggressive at NL50, just play your normal TAG winning game you used to play and you'll be fine...
Cheers
