Kevin,
You shouldn't feel you have to have dipsy's to catch fish, your rigger rods will serve you well. I fished last weekend and we still had a lot of spinny water fleas which clog up lines so you need to use large diameter line from your rod to the ball. I recommend you use 30 pound line (I like ANDE) for the vertical portion of your rigger lines then blood knot into lighter line for spoons or keep the heavy mono for the flashers and fly presentation. If your targeting browns try to use a long lead of 60 feet and no more than 12 pound test leader for spoons. Although folks have been catching browns on flashers and flies spoons, such a natural born killer, die hard and alewife patterns have been taking the lion's share of them lately. They have also been effective on kings.
The flea situation may make using the 80 pound power-pro diffucult due to its's small diameter. You could run a heavy mono dipsy for steelhead which are often higher in the water column if you don't have time to set up for wire. As was mentioned above its good advice to use a rod with some backbone to handle the larger dipsy's size #1 and up.
