FWIW on my CS 36T I have 3/8 on all my control lines like traveller, vang, pole lift, foreguy. 3/8 is fine on the hand and anything bigger for your boat would be a waste of money, and a lot of money if you want blocks tht will run 1/2 or 7/8 smoothly. Pole controls are pretty much set and forget...my foreguy trims through a clutch and works fine without any leverage or turns. The pole lift runs through a clutch to a winch, needed mostly just for lifting the heavy pole...
