Rickochet I had one of those in the red and it was huge. I have played a silver Triad II for about 10 years and don't see it going anywhere. I have a back up as well. One of the best putters ever in my opinion. Great machining and the weight adjustment options are incredible.
I have had mine since I think 2008. I have taken it out of the bag a few times, but only for very short stints. It finds it's way back in.
I did go out and grab 3 balls and stick them on top and they don't fit, so I guess the 3-ball is larger.
The Doc 17 still beats the 3-ball though for overall size and ugliness:
