I don't know how far I cast but it's definetely not 125 yrds. I love gibbs
poppers and feel they are one of the only plugs that float well. I did have the
same problem with the polaris sinking at the end of the cast. There are two
things going on. One: when the plug hits the water there is usually a lot
of slack in the line. If you don't take the slack out of the line before the
plug hit the water you will usually get the sinking effect. This is more
prevelent on long casts. What I do is flip the bail just before the plug hits
the water and reel the slack quickly and immedialtely start working the plug.
In other words, "don't give the plug any time to sink. Keep it on top from
the second it hits the water".
Second: If you are using mono there is a lot of stretch in the line. The
amount of stretch is proportional to the length of cast and line test that
your using. The lower lb test will stretch more than say 25 or 30 at the
same distance. Your line is basically a long rubber band. There may be
too much strech in your line. The line simply does not exert enough force
on the plug at the end of the cast to keep
it above the water. Most of the rod energy is put into
stretching the line and not moving the plug. As you reel the distance
gets shorter and the line stretches less and evetually the correct force
is put on the plug to keep it on top. May be the answer is to try some
heavier line. I know, than you won't be able to cast 125yds.
If I take out the slack before the plug hit the water I usually can keep the
plug on top regardless of the line stretch.
Just a few things to think about. Hope I helped a little.
