I have the Trophy Ridge Matrix as well. I find the pins difficult to see. Especially when the sun is behind me - the dots just disappear and all I see is a big post. I have found I need to use the glow sticks even during the day to overcome this.

I just purchased a Vital Bow Gear Trapper sight. This thing is extremely bright! No washout of pins in any light condition. In fact, the dots are sometimes too bright. I' m not sure of the size but the dots are about 3 times larger than the Matrix. I have not tried it yet in the dim legal hours but testing it in my driveway I had no problem seeing the pins more than 30 minutes after sunset.
