mvalviarOh interesting. I missed that little blurb on the first link somehow. It doesn't really say what the differences are but the SL-2 says new anchors. Good to know there was actually a previous version of it and also confirmation that this drop is for the SL-2 versions.
Link is the first hit when you search for this item on amazon. It says there's a newer version of the product which is this: http://www.amazon.com/Peak-Design-Slide-Camera-SL-2/dp/B00ZH2PFTM/ref=dp_ob_title_sports
