Plug Diving Depth

I'm curious if any one has a good feel for how deep Tadpollies will dive. In the past I've mostly used wiggle warts (troll diving depth 10-18 ft per manufactures catalog), Hot shot #35s (Max dive depth 12 ft),and Hot shot #30s (Max dive depth 10 ft). Is the Tadpolly a shallow running plug, or will it get down deep like a wiggle wart?

Bout 8 feet on 12 lb., less if you go with heavier line.
