Some Dolphins are plan based while others are not.
If not, both the Dolphin and Monkey could have some challenges from a lack of focus on executing a plan. If this is the case, this pair could benefit from seeking external support to assist their focus, or by recognising this potential weakness and putting in appropriate disciplines, such as a regular review of activity, to reduce risk and inefficiency.
In saying this, some Dolphins are plan based, and if this is the case, the Dolphin can bring such focus to the partnership.
Dolphins may not have the tactical knack and activity drive of a Monkey and this is where Monkeys can certainly add value to this relationship.
