Best advice I ever got was from the forum: Make sure that the inside of the cage is white. I ued a titanium cage, and when I tracked pucks coming to me, I was looking through blocks of wire and felt like I was looking out of a prison.
With a white cage interior, when I look down to track pucks, then white washes out with the color of the ice, so all I see is puck (and ice), which is obviously what one would think one would want to see. My white steel cage is heavier than the titanium, but it's fine- I will take extra weight any day and the ease of puck tracking. The cage I have also has flattened steel wire in the areas that you look through, so again, just makes it wash out that much better when looking at other players and not noticing steel bars between me and them,
