I like vertical presentations for the blades, but a lot of people are casting/retrieving them too. You need a sensitive line [preferrably a braid] to do the casting and it won’t work in weeds/wood very well. Over-working a blade on a retrieve can muff your chances at a hit and I haven’t gotten to that level yet personally.
I do fish those jigging spoons [like Scenic’s Go Devil, CastMasters, Lindy’s Frostee Spoon and Custom”s Jigging Demon] during the summer months when craoppies are relating to deep structure like sunken trees or logs. When its hot out, I cast those critters paralell to the structure and use a winter finesse plastic on one of the treble’s hooks. Very effective when fished as such.
