I was thinking about a Genera mod to allow any input loading setting desired using two opamps and wanted some suggestions... I've attached my 1st schematic. I moved the final high-freq correction filter to between the opamps, which should take care of any slew issues in the high-gain stage. I don't really know what the best choice for the 1st amp is, but since it's not working very hard, I'd think noise would be the main concern.
