Generally, matching the bait size to the size of the fish you are targeting is key
Once the rig hits the bottom I pull up the slack in the line, and then drop the rod tip letting the bait fall back down again
It does not rust even when exposed to salt water, and can be used safely in the sea
A graph from Shimano's website showing the grouping, and the first question that comes to mind is why, for instance, would a Stradic benefit from the momentum of a heavier plastic rotor yet the Twin Power XD wouldn't
The rods backbone will do most of the fighting
You can load a rod enough to get the spool spinning faster than the line will come off the reel and control spool speed with your thumb, by doing this the object being cast is only slowed by the drag of the line through the air and guides
