I do not have one of these, but remember owners saying they prefer a higher brace height (around 8" to 8.5").
I've been looking for one of those for a while, and did see one here on the classifieds in a "heavier" weight than I could handle.
It seems there are a few followers of the SDM who know lots about them, with one being "Frisky" who frequents the *********** quite a bit.
Got pics of your SDM to post? What are the specs?
