What do you prefer?
Personally, I like a 7-foot one-piece in either ultralight/fast that is good down to 1/32 or a 7-foot light/extra fast good down to 1/16. and most of my rods fall into this length range. I like either rod to top out at 1/4 or 5/16. I seldom fish over 4 pound line and prefer Trilene XL mono, clear, for the basic jig/plastic stuff when the jig weight can range from 1/32 to about 1/16, sometimes as much as 3/32. I do have a couple rods spooled with 6 pound Clam Frost ice line that I use for vertical applications, especially with #3 Rippin Raps or 3/32 heads and plastics that have a bit of profile to them.
Years ago I started the ultra light to light craze with rods in the 5-1/2 foot length but shortly thereafter started to favor 6 foot. After a few seasons with a 6 I began finding favor with 6-1/2 to 7 foot rods and now any open water rod that I use regularly thru the open water season are 7 footers, mostly of the light action ilk. I do have a couple custom builds that are six foot and are rated down to 1/64 that see action only from docks in the very late fall where fishing the pilings is done using 2 pound braid.
Rods longer than 7 feet seem to be too whippy to me. I’ve played with the 9 to 12 foot rods enough to know they are the pits for my style of fishing.
So what do ya’ll use? And why?
