To whom it may concern. Well I found a great write-up on the Bilstein 5100 in relation to spacers, shock extenders and the use of different bump stops. It was well written for what it is. (Exaggeration alert) including 27 8x10 color glossies with circles and arrows and a paragraph on the back of each one ( yes, Alice's Restaurant).
Bottom line I'm happy to say I'm well enough educated on the pertinent working differences of these basic systems. Better than most anyone could have explained it, considering most likely don't know themselves. I'm sure the majority of users take the word of others rather than actually knowing the when, where and why of things themselves. And as I thought, valving is irrelevant as that mannerism can be implemented with other systems. But that's not in the read, let's just call that common sense. Here's the link for anyone interested.
