It's NOT a change of routine, it's a more complex progression plan that you are ready for.
I hurt myself really badly because I didn't evolve from Starting Strength when I should of. It's a great routine, but I think if one is going to push it too far they need a coach there watching them and telling them when to back off, when form is breaking down, etc. And that is simply not an option for 99% of us.
I never used the texas method, but it seems like a very prudent next step. You could also do Madcow 5x5. I did that routine, it was good, although when I compare it to the texas method I will admit the texas method is more appealing on paper.
If you are interested in a more "bodybuilder" type approach you could try a 3 day a week Heavy/Light/Medium full body. I actually have one specifically in mind if you are interested in the link.
