The AOA Match Service opens June/July

So basically by the time you start clinical rotation, and have just finished COMLEX 1, you will be getting your application together to apply for residency. If you do the bridge, the downside is ... you won't have any clinical rotation scores or grades. Your dean's letter (MSPE) will talk about your preclinical grades, but nothing about your clinical rotations (as a DO student, not as a PA student). Basically you will be applying without any significant core rotations to a competitive field (surgery, anesthesia, emergency medicine, ortho, etc). And if the program lets you apply to acgme residency - not only are you fighting an uphill battle (as a DO student), but you will be fighting an uphill battle without any relevant core rotations grade.
And you won't have any recent LOR from rotations.
Plus, you will be missing days on rotation for interviews. It will certainly affect your performance, or the perception of your performance (since you will be missing multiple days for your interviews on CORE rotations)
The bridge may let you graduate faster, but the logistics of applying for residency (AOA/ACGME) will be a nightmare (and partly why LECOM's APAP primary care pathway leads to LECOM primary care residency, or why NYU's proposed 3 year program lead to NYU residencies).
