i have tried to pull double duty, and did for a few years with some daiwa med-light rods. they worked OK but they tore the hooks out of the fish's mouth in winni too often. In my opinion you really need 2 sets of rods i am sure some get away with 1 set like i did for years but from experiance i couldn't get it to work out and eventually bought a bunch of the eagle claw sf407 noodle rods for winni and left the others for ontario.
i also did double duty with daiwa sg27lca reels spooled with 17lb. test and then i just tied a piece of 6lb. leader on when i was at winni. This worked OK as well and i used this method for many years but i found that those reels didn't have the drag flexibility i wanted and if just your pinky finger touched the drag lever it would tighten it up too much and tear hooks or break line.
some rods that i found to be better for double duty are the eagle claw sf400 7'6" 8-15lb line rated.
and the cabelas depthmaster DM86 it has some good noodle to it with some backbone too it ain't too bad.
you would need something the size of an Okuma Magda 30 for double duty the 15 and 20 are too small.
