The best set up for a standard 225 Opti is a 26 Trophy or Tempest on some. There is no standard, though this will give you a guideline. We would get our dealership to help with the set up and some on water training. It is a big step from your 17 aluminum to a Puma. A little like moving from Mini Cooper to a Suburban. Things react quite differently on a big boat. There really is an education and a learning curve. We will be glad to help answer any questions you have here.
