Mister Twister

Has anyone had any luck using the Salmon Prop made by Mister Twister. I bought a couple last year when they hit the store shelves, but haven't used them yet. They seem a bit pricey to be used while drift fishing. Maybe behind a diver or plunked perhaps?

Yes my friend who was in Portland over the holidays and fished Melldrum Bar on the Willamette saw peope useing them as the top piece on a rig that was using a two inch split tail pink grub only. No eggs or bait. Wasn't sure about scent. They were plunking and were catching fish on it.
