Hey KM & Rock!
Sorry for my late response but I've been up in the San Juans grinding out a few strikes.
I'll post up some pics later but to answer your question....
Yup, when you hook up on the Slider Spoon you're gonna have a bit of a mess to clean up but I have not lost any fish because of the slider...
Quite to the contrary, if you weren't running that spoon...you probably wouldn't have hooked that mid-water column critter in the first place!!!
