I just replaced all my tru glow that I had in my hoyt rest with cobra pins. I did not like how thick the tru glow posts where. I replaced all my pins with all red cobra pins and can see the pin well. I was out yesterday and could see my pins in the shade clear up to sunset. The cobra pins are only 3 to 4 bucks a peace and you can get them just about any where. Just make sure to get the kind that fit the pin rest on the sight you are using.Cobra makes different sizes to accomidate the different rests. The pins are a little shorter, but you can simply adjust yoursights after replacing the pins. Just mark where your old pins were before you remove them, measure the differenc between the old pins and the new ones and adjust your windage that much and everything should be right on. That is if you dont like the pins you are using. If you are ok with them, Id simply replace the light colors with the color you see the best. I too have trouble seeing the lime green pins. I use all the same color. Its easy enough to know my top pin is 20 and the next 30 then 40 then 50. No problem with using the wrong pin, that is unless you have programed yourself to look for color rather than possition.
