I find that the playing ability in these limits vary much more than a larger limit game or a tourney probably due to varying bankrolls. Its real important to identify the different calibre of the players at your table because of this. I also find that the players talk to much at these games and reveal too much about previous inexperience in such games.
As a final note, 1/2 and 2/5 are games more vulnerable to a large stack steam rolling the entire table because of the number of players not buying in for the max and I think thats where your value is in these games if you are a solid player.
