As a Manzella labeled "swinger" I see my delivery path on more of an arc with a sweep type of release. I haven't met too many people that are happy with the way their swings look on film and I'm no exception. I would love to have a more delayed trigger release with a straighter delivery. Would this be more for looks than results?
The sooner you begin the Release, the higher the Handspeed required to achieve a given distance. Therefore, all else equal, the short, quick arc of the Snap Release will produce greater distance than the Sweep Release.
