The fixed six meets most of my needs as well. The Meopta MeoPro 6x42 is perfect for me. It doesn't need to be improved or upgraded.
My one concern is whether it will continue to be available. It shared a common tube with the MeoPro 3-9x42 which is discontinued. Since then the price has increased and it is not always in stock. I addressed this concern by buying several that I found at a reasonable price as spares. I am using six and have three in reserve.
There would be no return on investment for further development of a fixed power scope for me.
If it's like my 3-9x42 I wouldn't mind an upgrade to the adjustment labels with an adjustable zero marker.
