Reading above, JungleJim, with his usual fish taking wisdom, reminds me of an important Boolie, trout catching fact! Yes, keep reeling SLOWLY after a trout attack ; I've OBSERVED that larger trout ,in particular, sometimes strike so fast& aggressively that they "bunt" the boolie away,but realize their mistake and instantly circle back (and I do mean INSTANTLY-talk about " turning on a dime"!).If the boolie is allowed a slight slowdown or even a drop, I guess they feel that they've stunned their prey and lap it up -there is almost NO missing on the explosive retake (with good sharp hooks!). Now, if you'd tried to "Set" the hook hard,you jet it away from the vicinity& a hungry,eager trout!
Another trick worth considering -if trout seem closed mouthed on a slow day, try LENGTHENING you boolie to encourage strikes! Last season I went most of a morning with nothing,while my 31 yr old son limited (not that we keep any,but this is a minimum benchmark with Boolies!). I observed that he had tied his Bool with 1 1/2" zonker strip, which HIS rainbows obviously enjoyed! Since we had 10 minutes more to work before leaving for home, I informed the always wisecracking, razzing Sean of my secret catch-up tactic! I placed on the jig a 2"ultra thin strip of light blue plastic grocery bag material. To his consternation I limited out in that short period, to very aggressive takes! By the way, I've just discovered a new grocery stores that have soft purple, translucent carry-out bags -can't wait to "bool" these through the new trout when they stock (hey, that's TODAY !!).
