I have been on an Albe 24 w/ jackshaft. It moves the weight forward so the boat isnt so transom heavy. This allows the boat to plane quickly and run more level, especially at slower speeds. On a variable degree hull like the Judge it will allow you to better get the boat's sharp entry down into rougher water for a nicer ride. The jackshaft also gives you a clean transom to fish over. If you are going with an outdrive and can afford the jackshaft, I believe it is the way to go. Just my opinion!
There is a reason top builders like Albemarle and Carolina Classic only run jackshafts with outdrives today.
