Get the compact if you are absolutely set on getting something smaller, but you would probably be okay on the standard with a decent sized rear cassette sprocket setup.
Standard double rings are 53-39. Road triples are often 53-39-30. You can have the exact same gears as on the double plus a lower set. Or ride a cassette with a big cog two sizes smaller to fill in the gaps if you want to ride exactly 80 RPM; although with a little training you should have no problem spinning 100 RPM for as long as it takes.
