The added travel is right at the end of the shocks stroke. So, if you remove the spacer, and set the sag up to the same percentage it'll be slacker.
Thanks for the confirmation.. seems like I might be out of options for steepening the HTA then - other than expensive ones like replacing the fork or shock. From what I understand an offset bushing will only slacken and can't be reversed. An angleset doesn't work with the knock block either I think?
