I guess I'd have to ask, why fly a Cub without them? Or any other model of a full scale plane that had them.
If you don't want to fly a plane with struts, buy a plane that doesn't have them.
In my opinion, nothing looks worse than a "scale" airplane like the Cub flying without struts. (Well, maybe a jet with a prop on the nose, or most fun-fly plans, or profile planes, or....

)
