I hire a 172 and it only has 1 Com
It's more important to stay in contact with the controlling agency (if in controlled airspace) than to listen to the ATIS. If you did not get the ATIS letter and info somehow, simply say nothing about the weather and on first contact the tower will tell you what's important (usually QNH, runway in use) and/or when you receive your landing clearance (current wind).
I have found that even if you do say the correct ATIS letter, they will usually tell you the QNH and runway in use anyway.
And those two are readback items of course.
As for the rest of the ATIS report, such as clouds and sigwx, well, you usually know the cloud situation and sigwx better than the met man in the tower. After all, you're in the middle of it.
