Not all Chinook are created equal. Is a big one #15? #20? #30? More
? One of my best pruchases was a 2 piece Sage Discovery II 12 wt many many years ago for about $120. It has caught a number of #30 pound fish and seems indescructible. for smaller fish I use a 9.5 foot scott STS 10 wt. It too has been a great performer and was also a closeout. So, I guess my answer is it depends on the size of the fish with a 10 wt being a good starting point. For a rod you aren't going to use much, I wouldn't hesitate to get a TFO or something similar in the $139 to $180 range and a unconditional warranty.
