Hi, in my experience, a too short cable should cause the condition you describe, not one that is too long. It sounds like your cable is binding somewhere. Check that out and re-route it if necesary before you replace anything. Let the excess stick up above the tank in a gentle loop; don't try to "tuck" it out of sight. Tight looping of cables will bind them. Then, if it works right, you can consider whether you do or don't like the look of it.
