I think that the pack is reasonably settled at the minute and they are getting better week by week. The all-Tah front row makes sense and I would stick with it, with the possible exception of Moore coming in for TPN. That's a 50/50 call for mine.
In the second row it pretty much has to be Sharpe and Simmons for the moment, though like many others I want to see Hugh Pyle get a run.
In the back row the task is slightly harder, basically because we have more depth. Bam obviously picks himself, but 6 and 8 are still fairly competitive. Cliffy has played better than I expected and I reckon he'll start there until someone comes up and takes the spot from him. Higgers has done pretty well at 6, but I've been impressed with Dennis in the minutes he's been on the paddock. A big improver amongst Australian forwards this domestic season.
So in summary, I would have:
Cat
Taf/Moore (can't split them)
Kepu
Sharpie
Simmons
Dennis
Bam
Cliffy
at the moment on form.
