Brandon, It all depends - if you are operating in the midst of normal strength signals, then you can use the full 2.7 (2.8) kHz bandwidth and select the station that you want anywhere on the waterfall display. However, if there is a lot of QRM and/or a strong signal that is taking over the AGC in the receiver, it is wise to narrow the bandwidth to select only the desired signal and perhaps turn off the AGC and reduce the RF Gain. That takes a bit more effort than the easy Click and QSO type operation, but if you really want the contact in the midst of QRM, that is the way to accomplish it. A 200 Hz roofing filter would be nice for those particular situations.
