I replaced my TA-11 with the USO 1.5-6 but that was a decade ago (custom one Frank had built and tested). Good move going towards a real scope in this application; old eyes here as well and that TA11 reticle gets smaller and smaller with every passing day.
You'll be very happy with it. I'm familiar with some of the other glass you have from your posts over on THR. If my 1-6x24 is representative, you'll be pleased.
