So both section of the 427s is diffrent from the SU's??I've had a few 427s and Su's. Butts on the new black ones are almost identical power wise. Tip on the std one is softer and more through action but a much better fishing rod with excellent bite detection for such a powerful rod they load beautifully with 175g and bait . Unless your capable of 260-270yds then the SU is likely to be too powerful and will feel rather numb. The middle and lower tips on the SU have some serious grunt. SU does however make a good hauler in the kelp.
