The only markings on this crankbait are on the lip (Rapala Deep Runner Ireland). It's 2.75 inches long (not counting the lip). Is it a #5-6-7? How deep does it run at lets say 2.5 mph with 100 feet of 10# XT?

I think I'm sure the "#" size on an Irish Rapala, and all other Rapalas, is the length of the lure in centimeters not including the lip. For instance, the body of a # 5 Rapala is mostly 2" long, and the body of a # 7 Rapala is near 2-3/4" long. 2-3/4" is real close to seven centimeters.
