Don't stress out your team by asking them to help make this decision. Communication and trust are essential for any new hire, so you must make sure that both will be possible. This is why I like to ask general questions, trying to find areas of common interest and distinctive behavior patterns. Hiring the wrong person can be disastrous for any organization, but so can hiring clones. You need to enrich your corporate gene pool by adding varied approaches, but at the same time avoid splitting into factions.
Alternatives are fine as long as they sit well in the established framework.
A good analogy comes from comparing rowing and football teams. In the former all the members work together in locked rhythm. In a football team each person has a specialty and usually cannot be moved from one area of the field to another. Work out the kind of team you want to build and make sure you hire folks that fit the model. Unless the team is underperforming and needs a collective boot up the backside you will need the cooperation of all the team members.
