Anyone try these? I'd love to see some of the followers and missed hits I never know about. Any recommendations or experiences with them appreciated. 

Not sure 'which' trolling camera you are speaking of. I can recommend the Water Wolf 'in-line' camera which you can use trolling, casting, from a bobber, or on the bottom. These cameras are really great and produce some fantastic videos. I must caution you tho, using these cameras could become habit forming!
