I've actually used the sling shot, breeze (pearl and hybrid), and super natural all with similar layouts in a 5 man league on a 37' house shot. For me I could play similar lines with the sling shot and super natural. The difference being the sling shot was longer with a sharper back end and the super natural was earlier with smoother back end. If I got the sling shot out a little too far I would have a chance of it coming back. However if I were to get the super natural out a little too far it wouldn't have the back end to get back. I had to move right with the breeze because for me it's weaker than both. If he gets a breeze I wouldn't lay it out weak. Has he considered the roto grip scream? To me it would be closer to the Sling Shot than the breeze or super natural in strength and shape.
