Drop Eagles DST for Cardinals DST? (Hear me out...)

[Wasp]

I'm seriously toying with the idea of dropping the Eagles DST for the Cards DST. They have both been performing well, but Arizona's upcoming schedule is RIDICULOUSLY soft. Take a look at Weeks 15/16 (my playoff weeks) to see who Arizona plays, here are the schedules:

Cards:
9 11/08/09 1:00pm @CHI
10 11/15/09 4:15pm SEA
11 11/22/09 4:05pm @STL
12 11/29/09 1:00pm @TEN
13 12/06/09 4:15pm MIN
14 12/14/09 8:30pm @SF
15 12/20/09 1:00pm @DET
16 12/27/09 4:05pm STL
17 01/03/10 4:15pm GB

Eagles:
9 11/08/09 8:20pm DAL
10 11/15/09 4:15pm @SD
11 11/22/09 8:20pm @CHI
12 11/29/09 1:00pm WAS
13 12/06/09 1:00pm @ATL
14 12/13/09 8:20pm @NYG
15 12/20/09 1:00pm SF
16 12/27/09 1:00pm DEN
17 01/03/10 1:00pm @DAL

Thoughts?
