I've been using the Soloist for years and routinely rope solo at the Exit's, as well as many other area's, sport or trad. The mechanics of the Soloist are simple and it's easy to see that it will lock up and catch a fall unless you flip upside down. If that is a possibility it's easy to back up the Soloist. Also it self feeds, although sometimes with significant rope drag(newer the rope the better). And it won't break the bank like the Silent Partner. When I'm rope soloing a sport route I usually use the first bolt for the anchor, unless there is a handy tree nearby. Then I clove hitch the rope to the second bolt/QDraw to be sure that the anchor biner is in the up position. So in effect I have two anchors. And yes, I am aware of the high fall factor. That being said you can usually plan on climbing below your limit, but it is a way to make easier climbs exciting again! I say go for it! But not bolt by bolt.
