I like leading 1/2 pot sometimes too with a made hand (or a strong draw) It's almost the same as checking and their reaction will often tip their hand. An aggressive play will almost always reraise thinking your 1/2 pot is a weak attempt to get a free card. Then you can choose to just call and go into the turn with a bigger pot (or push if you think you can get them to call).

I think a check-raise into two opps tips your hand way too much - especially on a board with limited draw potential. This line of thinking applies to 100NL.
