I had to go with H and Calleigh cause they compliment each toehr very well, Danny and Hawkes cause ya ned the guys with a attitudes, and the infamous Betting Duo of Warrick and Nick.
As I wartch all three, I thought back to the three crossover episodes and composed the team accordingly: the N.Y. members would be Mac and Danny, the Miami reps. would be Saint H. and Ryan and the Vegas group would be Catherine and Nick.
they should make a CSI movie....and have a case that starts in Miami, and it takes H and Ryan to Vegas, where they meet up with Cath and Warrick. and then the case takes them to NY, where they meet up with Mac and Stella. and they all end up back in Miami where they finish the case.
