I've never hunted Lynx or Wolf but I know that Coyotes can't resist the old tried and true Rabbit distress. Coyote vocals (howls) work good at certain times of the year too if you can master a howler.
Like I said "no personal experience with Wolves" but the guys that I know around here that have actually killed a few like fawn bleats and Coyote howls. (Wolves hate Coyotes but I'm sure you knew that).
Not Lynx but I've called quite a few Bobcat over the years with high pitched cottontail sounds. The higher the better. Matter of fact, the last Cat I called, all I had with me was one of those squeaker bulbs.
Luck
