I think a MH is likely too heavy for a 1/4th oz. swim jig . . . or nudging close to the operational lower end range bound. And, there are times when you might want to drop down to something even lighter, say down to a 1/8th to stir up a bite if it's really a tough day. Few things catch fish on tough days like going really small or in the direction of finesse.
If long casting distance is a goal, I'd at least look at a Medium power or even another MH power with a parabolic or moderate bend action, not a fast tip. You'll cast farther and, though it is harder to accept for many, you'll have more power over a fish once it is hooked since your lifting point will be closer to your hands.
