I dont think it is necessary at low limits. Alot of the time you will stack TT on a 9 high board, you will stack AT on a T high board even if you raise. Whats the point in playing it weak, all you are doing is preventing money from going into the pot.

If you are against a good player who has raised so that you are in position and you know he will put you on just AA/KK if you reraise then you might need to start getting trickier. Otherwise just do it.
