I have been useing the salmon roe power dip from berkley, I have had Mac's, Rainbows, and Browns hit my jigs even when they are not tipped. I have not tried it at Granby yet this year but I think it would be worth a shot. Good Luck. 8)
Haven't tried it at Granby, but I don't go anywhere without it.
I always use the Crawdaddy or Crawfish. No scientific evidence, but it seems to work, I've fished the same jigs side by side with the same bait tipping them and the one that has the smelly jelly on it seems to get the most fish, not more intrest or hits, but more catches. But that's just my experience.
When I am fishing for lakers and the bite has ended but you can still see some movement on the bottem on the Vex. I will dip the tube jig and sucker into some Berkley Roe and give it a few twitches on the bottom and 9 out of 10 times that laker is mine.
