Guys IIRC those big GShad above were 20 inches and 3 lbs. +-. Even assuming a LMB will eat something half its length (more like 1/4 to 1/3 but on shad 1/2 is not unreasonable)). Have you got LMB 40 inches ? At 40 inches you are talking 30 lb LMB. Can you say world record ?

40 X 40 X 24 / 1000 = 38.4
40 X 24 X 24/ 800 = 28.8
