There are a total of 24 rows in Section 328, with row AA being the 20th row from the front. Due to the large size of the section (there are a total of 46 seats in Row AA), there is an aisle which runs in the middle of the section (between seats 25 and 28 in Row AA). As you face the field from the section, seats 1-25 will be on the right half of the section (closer to the back of the endzone), while seats 28-48 are on the left half of the section (closer to midfield).
Of the seats you mentioned (41-48) seat 48 will be the best as it is on the aisle and closest to midfield for the best views of all areas of the field. All of the seating in Section 328 Row AA will be under the roof that runs along the sideline, and will be well protected from inclement weather.
