Personally I like lee jr's but for a walkaround you need to consider passage forward more then I do. There are some good hardtop mounted outriggers, but spend the extra money for a pair that does not flex much, some flex more then others. As far as length, 18ft or so would be ideal, 16ft min IMHO. A longer rigger will allow you to double rig them and get 2 lines off each outrigger which is ideal when conditions allow that many rods. Also, if you run bars, the higher the tip the further back you can run the bar without it digging in and spinning. The choice between hardtop mounted and lee hrs is hard, and really comes to personal preference. Some people want the space to walk around and would rather have them on top. Look wise lee jrs look more rugged but looks aren't everything, functionality is more important to most. Think about how often you go forward on your boat, is it mostly at the dock or not. Would you rather reach up high in the cabin but have something protruding down in the helm area or would you rather have a mount outside the cabin in your walkway taking up about 4 or so inches of space but places a mount down low where its easier to grab. Price wise you will be looking at similar prices. Best bet is look at pictures online of both styles and see what suits you best. In the end they both work just as well.
