Excuse me if I have double posted.
An 8ounce weight is my standard cast, normally with a 30lb line, no trace (ie straight to the swivel on the weight). I dont like whippy rods, so what I do is hang a weight from the tip and the rod should show an even curve. If the end bows over too much (to me) it means the rod will whip too much. The reason I dont like whippy rods is that I have a strong cast and when I am going for distance over accuracy can easily snap the line at start of the cast.
I also like a rod that has a good length from the reel to the bottom as I like the extra leverage and let the rod do all the work on the cast.
