I went super cheap with a short stury berkley big game from walmart. i think it was less than 30 maybe even just 20. it has caught plenty of coho and was a bit big so i bought a 6'6" for coho and use the 7 for nooks. they had a 7'6" but it had a lighter tip. A good cheap rod. but by know means the best. Someday I will upgrade to a 8-9' stiff nook rod. I might be totally wrong in my thinking of how i like my rods but cheap is cheap and what works works. Best trout trolling rods are 7' medium action baitcasting rods with small levelwinds on them.
For trolling for Kokanee and Trout (we all want 5lb trout but let's face it most trout in the 12-14 inch range) I would go with a 6ft light rod rated for 4-8lb or 6-12lb line or so. Throw some 6 or 8lb Maxima line on it and your good to go! For trolling for Salmon I'd go with a 7ft-7ft6inch heavy or medium heavy rod with a line rating of 20-40lbs or so. Throw some 30lb Maxima on that one and use 20lb leader. If your not to far away from Canby I would HIGHLY recommend checking out W.W. Grigg's, he has a store at his warehouse 3 rods for 100 I believe. Great rods at a great price! He has everything from UL trout rods to Halibut/Sturgeon setups! Lots of fly rods too!
