Leeds have the Zonker seal of approval @ 4/5 I think
Seriously though, Luton could go there and win 2-0, but they could more easily lose 3-0. They're a team that likes to play football and go for it. They do give you a chance, and with Leeds basing their tactics on solid defence, you'd think if Leeds can score first, they should do it.
You could also probably make a case for laying the draw given that Leeds don't draw much at home, nor Luton away. Also neither team would really gain much by drawing.
