I always wanted to tie a 2-3" piece of Red Yarn on my Jigging Raps to simulate blood; but never got around to it though. You could use scent on that. Dr Juice worked for me, not all day; but its good for a change up when the bite slows, not sure if its still around.
I did always use the little RED flipper that comes in the package on all my Swedish Pimples along with a larger treble hook.
That sounds like a great idea about the hot melt glue eggs too!
