question opamp with high SR and wide GBW

Hi,

I'm trying to design an two staged Op amp for a sample and hold ciruit with 125v/us slewrate and GBW>50 mhz with 60 degrees phase margin. My main problem is that i can t fullfill both gbw and phase margin requirement.

Am i doing something wrong or should i just use a different amplifier?

I posted my test circuit, internal design and my results. Any indication would be appreciated.
