You should use the tests at http://www.kitterman.com/spf/validate.html
to check your prospective records.
From a glance at compatibleweb.com, I think you simply have the wrong
prefix
v-spf1 ip4:66.235.180.161 -all
You want
v=spf1 ip4:66.235.180.161 -all
(note the '=').
Since SPF leverages generic TXT records, if you don't have the right
initial sequence, this record is treated as just any old text. But
don't just assume _not passing_ SPF is why Hotmail is sinking your
mail. It's not that you are failing SPF, you just have, in effect, no
SPF record. Yes, passing might help tip the balance. But also make
sure you pass the standard EHLO-PTR-A "DNS roundtrip" for outgoing
mail, etc....
