I have a Slide on both my bodies and really like them a lot. Quality and comfort with heavy cameras and long lenses.
For the BossStrap, which I mentioned on an earlier post, there is no gripping part. The over the shoulder, cross body strap is simple woven nylon or something similar, about 1.25 inches wide for its entire length. There is no fixed spot for the strap where it goes on your shoulder.
