I have been to rainy for the last 23 years but we go week before memorial day. We fish northern arm of rainy and the water is crystal clear. Can see bottom 10-15 foot down easy. We use number 8,10,and 12 husky jerks and X-raps in perch color, tennessee shad, and "white ghost" color. Bring lots and lots of white 3 inch twister tails on 1/8th oz jig heads. And like crappiemagnet said top water plugs are deadly especially as the water temps rise.
We kill the smallies on the northern arm using these tactics so I would asume the whole lake to be the same! Good luck and looking forward to the pictures!
