Definitely leave it at 2.7! I believe the firmware looks for either 2.7 (5-pole BW) or 2.8 (8-pole BW) for the TX filter so you might not be able to transmit with 2.6 selected. As Don W3FPR already stated, it is extremely unlikely most people could tell the difference with the filters offset by 70 Hz at the edge of the passband.
