That rod holder...no way! I would use a fishon! rod holder...they will lock your rod into place...as far as the scent spinner i beileve it would be a waste of time for sturgeon. Would try letting your bait sit in pro-cures sturgeon cocktail scent..good stuff. I also like to use smelt...They have a good scent in the water, and i know that its something the pike fisherman use up there so try that, it would be something they are used to seeing dead on the bottom and not all that unfamiliar to them.
