Trolling rods for salmon

Could someone explain to me how this 10 1/2 ft rod ( 12-25  test) won't break?

I mean if you are trolling a 2 pound weight, wouldn't the rod just bend to a point where it becomes useless?

12-25 lb test rod trolling a 2 lb weight doesn't sound right.

TL

The key is the length and moderate action of these rods.  They are a basically a big shock absorber and when that 2# ball drops, the long shock absorber will do a better job of keeping slack out of your line than a shorter or faster action rod.  There's a little bit of black magic in deciphering rod ratings sometimes, so there is no substitute for actually getting the blank in your hand and pulling on it to see if it will do what you want it to do.

Line ratings can be specified slightly differently by different manufacturers.  But the essence of the upper line rating is that when the line is pulled at 45 degrees or less, the line will break before the rod does.  This does not apply to high-sticking, which is a common cause of rod breakage, since higher angles make the rod more prone to breakage even within it's line ratings since the butt of the rod is no longer carrying the brunt of the load. 

The essence of the lower line rating is that the rod will still offer the desired action with line as light as that rating.  For example, using 15 # line on a rod that's rated for 30-80# test will not do very well at creating the desired rod action. 

Erik have you seen the New Seeker S-Glass Blanks?
 How is the action for trolling ?
Are the longer blanks all 1pc or are there some 2pc?
I was thinking of the Blue EX270.

I've never pulled on the EX270 but from the specs it looks like it might be a good multi-purpose blank.   Personally I think for trolling, a rod longer than 8 feet really is ideal though.  I don't believe any of them come in 2-piece.

I like the Blue Inshore Series blanks a lot... they are S-glass / graphite composite.  The CSW858 (8'6") has a nice live bait tip with good strength in the butt section to match.  Nice multi-purpose blank for our type of fishing.  I believe this is the model that Rockhopper recently purchased so you might check with him for a review.

S-glass is a higher modulus (stiffer) fiber than E-glass and is closer to a lower modulus graphite fiber, but has all the durability that is fiberglass.

Seeker will soon be releasing their "Super Seeker" blanks which will be S-Glass with an Epoxy resin system rather than a polyester resin system and these blanks are light and extremely strong.  Not sure what models they'll have but I think they'll be trying to match their Black Steel composite rod lineup.

cabelas has last years fibreglass magnum whupping sticks on sale.

might work for salmon trolling. I could not resist the 8'6" 12-25 roller guide model for $30. 
if nothing else it will make a great freshwater downrigger deployer.

if the link doesn't work, just put 'magnum whuppin' into the search box.

happy hunting.
