I find production/ss much more challeging, than limited. When I,m tiered, feeling lazy or it's going to rain I,ll shoot limited, other wise I enjoy the stage planing and find production/single stack to be more challenging. I,m in the minority but I think carrying optics should be 10 rounds and am not planning on shooting it until my eyes go. On a seperate note the 10 round limit would make things even for those states where you can have a mix of shooters some from mag limited states and some from no limit states
