Barry Greinstein advocates buying in short in his book. I have been trying it lately by buying in for 50BBs, and it has brought success so far. It also makes decision making with TPTK and overpairs very easy.

I have no sources, but I think that a solid player with good control will earn more from TPTK and overpair hands with a large stack than with a small stack, over the long run. I am not one of those players.
