Confused, your posts indicate that meeting as many houses as possible is very important to you. Your choice sounds more like one between informal now or formal in the Fall. Choosing the latter means just looking at groups now with the goal of pursuing a bid in the Fall. You do not sound at all comfortable with the bid in front of you because you haven't seen the houses. If that is truly the case, decline and go see as many houses as possible now and look for a bid next year. The current houses may or may not consider you next year, but if you graciously decline with, "Thank you, but I have decided instead to go through formal recruitment next fall since I missed it this year" you won't burn bridges. You can still visit houses. Then be friendly to every member in the two houses that you encounter -- always wave or say hi. Make every effort to meet women in all of the sororities so that you are better prepared in the Fall. Stop worrying about recruitment structure as that is a pointless worry.
