I agree with Alphahawk and use the TM and similar baits a lot. I use more 4# than 2#, but I do use the 2. (I'm far more worried about losing jigs than I am about losing fish.)

On a related note, I picked up a copy of Bassmaster magazine recently. There's an article about Aaron Martens and his dropshot methods. He talks about how he was using 5# line -- in a bass tournament -- but wished he had been using 3# because he knew he could have gotten more bites on the 3.
