I remember reading one time that someone trims the tails of their slammer. How much do you trim and how do you get the tail off and back on? Are there nails or just glue holding it in. Also why do you trim the tail? Better action? I threw mine for the first time last week and had some followers but no takers. Drove me nuts. Also how do you get a soft presentation throwing this lure. I think that might have been half my problem. Thanks...
