There is alot said here that warrants a seperate discussion. While it is true that each of us has preferences as to what and how we fish, some statements defy reality. I'm a bottom/plastic's guy, and I cannot speak to surface lures and such, but perhaps it's time to explore "Slack line bites".
If you felt it, and all forces are considered, you did not have slack line.
After fishing many years starting with the old black cotton line, through Mono and flouro, there is no line more sensitive than braided superline. As for 832 not sinking, that is incorrect. Having tested bouyancy with several monos, Floros and assorted braids, I have found the following.
Regular Braid and Mono float. Sink these lines and they will resurface.
Flouro sinks after the surface tension is broken. It sinks relatively quickly and stays on the bottom.
Suffix 832 sinks after surface tension is broken and stays down until air molecules attack themselves to the line and then it sufaces. It's sink rate is much slower than flouro.
Spiderwire Flourobraid, which has more of the Gore fiber than 832 also sinks and sinks at a rate almost as fast as Flouro.
I still play with flouro looking for the perfect blend of near zero stretch with managability, but so far it has eluded me. As for now, I'll stick with my braided line and flouro leader.
