hi mike, let met take a wild guess, the 6to7 pounders were females and the 3to4's were males, at leat thats what i've been running in to we've been dooing pretty good, for those interested try a small o/o sep's flasher with the green prissim so far that been my hot ticket with a herring helmet speed about 1.8. herring roll more importanr than speed, get good action and 3.0 is not nessary the males seem to be running smaller?
