Well designed roll-off in the low end tends to counteract the boominess' that is peculiar to the directional microphone. High end roll-off, though not desirable when listening to the piccolos, will help in reducing sibilance and scratch. Finally, a wide, even midrange with minimal variation will give a luxuriant presence to dialogue and effects. Slip-on fabric mesh screens are superbly adaptable for television and motion picture. We see with the mind, but we hear with the heart.
Clear sound is a joy.
Suspension mounts, otherwise known as shock-mounts both support the microphone and windscreen plus provide isolation from the microphone boom, camcorder or other means of support. A quality mount will be physically adaptable, but most importantly, be able to prevent handling noise, cable rattle, etc. from reaching the microphone. This transposing process can be likened to the suspension of a road vehicle where the disturbing bumps and jolts are turned into a long soft floating rise and fall. The deeper the give, the smoother and quieter the ride. Typically, however, it is not shock that is the enemy.
