Matt -
It sounds like you have considered various houses and are comfortable with one in particular. That is good and an advantage to "early rush".
However, I would like to pass along this bit of advice.
Between now and when bids are given out, something may happen. For better or for worse. And it may change your feeling toward the current GLO you like. So keep an open mind and your options available.
On a personal note, I had an similar experience - somewhat.
I grew up in a college town and was rushed as a high school senior as well. However, I attended college out of town so my "early rush" was not specific to joining one of the Hometown U.'s chapters, but rushed to join the "national" fraternity.
Of the 22 fraternities at my university, eleven had chapters on my Hometown U.'s campus. There was one additional fraternity for a total of twelve fraternities at the Hometown U. But only the eleven rushed me. Of the eleven, I had friends in six of the fraternities. So while I was rushed by all, it was the six - where my friends were members - that had the greatest influence and advantage with me when I began my "official rush" that fall on my campus.
Since chapters are different campus to campus, I kept an open mind. And granted, this may be different from your situation, but keeping an open mind between my "early rush" and when it came time to accepting my bid insured that I made the right choice.
Best of luck.
