I've never got one that was a true 20 pounds, but I got my dad a nice 40" pike last summer, and a 38" last winter. My personal best is 38". I caught mine on a lake that tops out at 11', and I was between two basins in 4' of water. The two pike I got my dad were both on deeper lakes, and both came off the edge of a big flat, just on the inside of the weeds, in about 10' of water. I don't get to fish in March-April, but I know that you wont find them in those spots any other time of the year.
