First of all I really love the sight,but as you have learned the pins don't glow that much.Granted,each fiber optic is several inches long so I have found these sights to glow more than enough in normal hunting conditions.The reason I had planed on using the Nitro light source was when I huntd out of my black-backed Double Bull blind. With these dark blinds you may loose up to 15-20 minutes of shooting time because you can't see your pins. I was a little disappointed by the fact that Trophy Ridges' claim to "no pin halo" actually means "pins glow hardly at all". As far as extra light sticks don't spend the $5 to $8 for 5 sticks when you can buy them from the source for .50 apiece or $22 for 50.
