NL vs PL

[Vecernicek]

I've played for 12+ months on PLHE FR tables, and I have consistently profited. I am considering moving upstakes (to .50), but on the OnGame Network, there are very few PL tables above .25. So, before moving up, I've decided to shift to 25NL, and see how I fare. It's still far too early to tell, but after a decent start over several sessions, I've had a brutal run and now I'm about even since the shift. I'm not certain how much I'm running bad, or how much I'm not adjusting (of course, it could be I'm making mistakes that would apply to PLHE as well).

I'm curious if anybody has any tips for me; maybe a few adjustments that I should be making. I'm kind of frustrated at the moment. What are the crucial differences I should be aware of?
