Spatial Join and Dissolve

Hi Guys, 

I'm stuck with a bit of a challenge. I have a grid and multiple polygons (buffered points). Each polygon has attributes and may cross multiple grid squares. I need to know for each grid what the polygon is with the highest value for a particular attribute, but also all of the other attributes.

A spatial join of grid to polygon gives me every polygon and it's corresponding intersected grids. In theory I then need to dissolve these to be left with only the polygon per grid with the highest value for the particular attribute. I just cannot achieve this? The dissolve leaves me with the grid and highest attribute, but not all of the other attributes for that polygon.

Any ideas? ArcMap basic licensing..

Dissolve does an aggregation of the attributes based on the dissolve field and the statistics_fields that are specfied

You would need the ID of the shape containing the maximum in order to join the rest of the data back
