bilstein HD v. comforts?

[B300FO]

For anyone with experience with them, which shock have you preferred for the W123 (Bilstein HD or comfort)? I have been shopping for the HDs front and rear, but have been told they might ride too harshly.

They will go on an '84 300D with 16x8 wheels and 225/50-16 Michelins. The previous owner put on some bargain shocks which are shot.

Thanx, Jeff
