Have run across this term a couple times lately and wondering what in the setup causes this. It really is the best way to label the feel of my susp. Whack whack whack thud thud thud pound pound pound. The only difference is the speed of hitting the obstacle and its size. Never feels like it actually absorbs anything. I am still looking for a active but controlled, plush feel that is linear up to light bottoming. What is the difference in the valving setups? I'm missing something when I communicate with my tuner, he is a great guy but we are just not on the same page. maybe its this "dead feel" philosophy. Thanks.
