Remember that the longer the rod, the more "cushion" or shock abosorbance you get when fighting fish. Essentially the same concept described as "noodly" by dogfish.
One more thing to remember:
Sensitivity is always sacrificed with longer rods compared to an equivalent weight/line rating rod of shorter length.
The
pros of a longer rod for driftfishing are:
-Able to keep more line off the water by mending
-Longer casting range
The
cons of a longer rod for driftfishing are:
-"Spongy" feel and more travel to rod butt (rember that's wher you hold onto it)
-More distance from tip to backbone, meaning that you have to move the rod a lot further during a hookset or when lifiting up and over rocks, trees, etc. before you get to the "ass" of the rod because of moderate/moderate light/ultralight rating. In float fishing, it's visual so you se the float move and you crank down tight and unload. Drift fishing you are going by feel and you'd better have some ass (backbone) to that rod and preferably a fast/moderate fast action so you can add tension, feel the bite, and unload like a U.S. Military convoy on some Iraqui soldiers!
IMHO - Be versatile and if one or the other is working for you, then don't worry about it. In a perfect world we would have rods to meet every condition, but if I had to pick two
-1025 for most driftfishing applications
-1263/1264 for float fishing
