Best thing to do is go look at them and see what is most visible for YOU. In my experience the larger diameter pins work better the worse someones eyes are.
So you might want to take a look at .019 pins but be sure and compare them to .029 and maybe even .039 pins.
The Spot Hogg sights with the Hogg wrap is also a good choice, as are the HHA sights. They do have the 10' of fiber optic available.
