Week 10 roster please help!!

[righthandman69]

For week 10, i wanted to list me roster and just reassure myself that i am starting the right guys. Particularly my Flex options. Please give me your takes, much appreciated:

STARTERS
QBs
Matt Ryan @ NO
P. Manning @ CAR

RBs
A. Foster @ CHI
M. Forte @ HOU

WRs
M. Wallace v KC
E. Decker @ CAR

TE
H. Miller v KC

FLEX
M. Williams v SD

Bears D/ST

KICKER
J. Hanson @ MIN

My bench consists of the following:

McFadden
Pettigrew
M. Austin
James Jones and Cobb both BYE week
C. Palmer
Rashad Jennings
Danny Amendola

My main concern is that i am using the best flex option. Williams has been consistent lately but i'm wondering if Austin will do better? I don't want to start Amendola just yet. What does everyone think of my logic on this and the rest of my starters? Some are no brainers i realize this, also Forte and Foster have bad matchups but i can't bench these guys for obvious reasons. Does anyone think i should change something and if so why? Thanks in advance.
