I favor the biggest corkie you can get (within reason) as in bouncy water or low light those corkies are hard to see.

Also when you use your toothpick, peg the corkie from the bottom side. Othewise the leader gets hung up between the toothpick and corkie.

One other chronie imitation I play with is slide a red or clear bead (silver lined), your choice of color, up a hook and then wrap the hook with green or red wire. They sink fast and while they don't shine like Phil's chronies do work. I can "tie" those up in about 45 seconds.
