The escape artist skill description on page 62 says:

"Ropes: The DC of your Escape Artist check is equal to the binder’s combat maneuver bonus +10."

However, the grapple discussion on page 151 says:

"If you have your target pinned or otherwise restrained, or unconscious, you can use rope to tie them up. This works like a pin effect, but with a + 5 circumstance bonus to determine the DC to escape the bonds (making the DC equal to 20 + your CMB). The ropes do not need to make a check every round to maintain the pin. If you are grappling the target, you can attempt to tie him up in ropes, but doing so requires a combat maneuver check at a –10 penalty."

Which is correct? 10+CMB or 20+CMB?

Can you make a CMB grapple check to escape from ropes, in place of an escape artist check (the words "like a pin effect" on page 151 imply that you can)?
