I have a Track Flamin T clear that is awesome looking, even better than the spare tire. The Hammer Everclear is pretty cool looking as well.
But you can decide, I've attached a pic of my small collection of clear balls.
As for a good looking non-clear ball it's a tie for me between the Legends World Class Reactive and the Seismic Solaris Platinum. Both are awesome looking.
Or any solid black shiny ball looks great too.
I can only imagine the FULL collection!
It's somewhat easy to imagine actually. There are three racks like the one in the picture, each has six shelves, the balls in the pic is on the top two shelves. The bottom four shelves each have ten balls. The other two racks have ten balls per shelf and are full.
And there are maybe 15 or so sitting on the floor that do not fit on the racks.
But that's just the undrilled ones...
