everyone likes different riggers for different reasons
some suit a certain boat's layout or an anglers fishing style (ie. some guys fish very deep with heavier balls, like 15lbs or more..)
ive used them all, and my boat has Scotty Pro Packs 116's, a little bulky yes, but very fast durable and fucntional
mind you though, if you know that you never plan to fish deeper then 50 feet down, then go manuals all the way! (walker or cannon make the best manuals) Much less to worry about with manuals.
