Quoted from ChadTower:A pin2k is so heavy that the CRT doesn't affect weight much. We're talking about a ~5% difference at most in the overall weight of the game.
I guess... if you aren't moving it anywhere. I routed mine for a little bit, and unlike a standard game that I can break down and move myself easily, the head of a PB2K game is so freaking heavy with the monitor in there that it really requires two people to take it apart and move it around. Getting it exactly on it's head bolts is also rather annoying.
If you can drop that 5% of weight 100% from the head, the difference is making it easy for one person to move / set up the game versus making you really need a second person. I understand that this is a need that not many of you probably even think about, but for a person who says:
...this should be a big consideration. Also, I don't sell stuff that I get generally, so it means that I'm going to have it around, and be moving it around for a while.
