What a work of love for WP suspension. Don't apologize for anything, your work is just great and none of this is simple stuff.
The WP fork is really an excellent component and easily adjustable but as you pointed out, much misunderstood. I can recommend Z-dogs stacks. Your work on the rebound needle is priceless. Get the right spring for your weight and a great suspension is born.
When I traveled in Asia I saw so many broken or leaking suspensions it was ridiculous. Beemers, Kaws, Suzuki, Yams, you name it, it failed.
I never saw a WP fork with a problem.
Thanks for your efforts.
