I like the Titans here. They're the form side of the competition (furthermore since Canberra were eliminated), having only lost to the Sharks in about the last 10 weeks. That loss may not have been the worst thing, as teams have struggled to win any more than 5 or 6 on the trot all year.
They've ground out some really great away wins in that time (Dragons, Warriors, Roosters) and I like their steely resolve. Most of their players are either at their peak or in their twilights, so there's no better chance for them to make a Grand Final.
The Roosters have been pretty good over the last few weeks, and are a side that can beat the Titans if they put it together. Hell, they turned their season around with a resounding win at Skilled Park midway through this season. I just question the selection of BJ Leilua on the wing - even though Phil Graham has lost the Roosters games this season. If Gordon and Zillman get into space...
