Why dead stick? Just jig with something flashy, bows will hit anything moving or flashy.
OP is talking deadstick for BIG lakers which is a far cry from the small bows a number of guys are replying about. Senko worm is an interesting option, as you always hear about finding lakers with tonnes of old bass plastics in their stomachs if on a lake that has both species. I would think it would need to be near/on bottom to work, but you could try suspended as well. Around here it is usually a big tube jig or paddle tail swimbait on the deadstick. Scents really haven't found their way into swimbaits yet, so you could give them a go. You could also try upsizing to some of the 6-10" musky swimbaits that are out there and see if the trout like that more than the 4"
