I'd say he shouldn't make a judgement before going through rush. Tell him to go where he thinks he'll best fit in. Have him ask serious questions about what is expected of him as a new member. Most of all he needs to be himself. Rush for men is MUCH more laid back than I understand it is for women.

Just tell him to go through, meet everyone he can, give everyone a fair shot and then make a judgement.
