Hi there. Mcarthy plastics would be you're best. They are well priced and work like a bomb. The 5inch on a 3/4 to 1.5oz head and the 7inch on a 1oz to 2oz head. 2oz is often a bit heavy for around the reef areas so if you can cast the 1oz far enough I would prefer to use that weight. As far as colours go they all work well but I've done well on cob using the darker colours and the pink and the chartrues works well too.
