Yes ... 14' rods other than PST's or Power Trollers are not as stiff. And the Power Troller would be stiffer than a PST. My 14' Capps/Coleman rods are not as stiff as my 14' PST. I'm not sure about the BGJP's and where in the lineup they fall, because I only have a 12' BGJP rod, but I'd think it would be less stiff than my C/C rods. I'd also think the 14' Diamond Series would be less stiff than a BGJP.
Look at the weight range & line size range of each model for more telling info.
