My preffered rotation, please help

[great gretzky]

I play in a league with a lot of bench spots to think it out (10 team keeper).

Anyway, We start 6 stareters, 4rp, 2 p. What should be my money guys, which should be my trade fodder? I realize who my best guys are, but I'm wondering about value, and who I shoudl gamble on to a degree to maximize later trades.

halladay, smoltz, verlander, willis, hudson

anibal sanchez, glavine, gorxelanny, james shields.

there's no way I can pitch them all, even with spot starting....
