Am I taking my limit "way ahead, way behind" theory too far?

[odawg09090]

I used to be a hardcore limit player but recently switched over. In limit, when we're probably way ahead or way behind, we're supposed to play like a calling station and just call. Raising does us no good because it lets them escape cheaply while folding might make us fold the best hand. In no limit, taking this theory too far can be expensive. What do you think about these two hands?

Both hands are from 5/10 NL on Full Tilt.

Comments: The villian in hand 1 seemed a little aggressive so I called him down. The villian in hand 2 seemed tight and rather passive so I figured he had a lower ace. I don't know anymore but I'm starting to think calling POT POT POT on the flop, turn and river with just a pair (with a great kicker) is a losing play EVwise. Maybe a turn mini-raise for a free showdown is cheaper and a better play? Maybe calling the turn and folding the river is a better play beause no reasonable villian fires 3 barrels, right?

What do you guys think?
