Interesting you mention "blades".  My buddy who fishes the river freq. in the fall and spring runs uses a blade above his jig like this.....place a clevis about a foot above your jig, place your fav blade in it, then loop your line back around and through the clevis, then tie on your jig.  He claims it works well, doesn't kink his line at the clevis and he's convinced it increases visability.  I've yet ot try it.

The Spring run up the Rainey is phenomenal.  They rip several feet of ice off the river by opening the dam discharge on April 1st.  When that finally opens out to Pine Island near Baudette on Lake of the Woods....the bait and the big momma 'eyes come flying up river.  Problem is....crowds are nasty, landings are nasty, people get nasty, weather is nasty...DNR says you can only have 2 spring fish.  So I opt to skip it and stay to the fall run.

What type of blade rig do you work all day?
