The yakuza is a nice board but for some reason it doesn't have classic/sniper mode like all the other boards I've used (was, pandora, utb, e2). The yakuza is the easiest to update and will allow you to change fire modes on the fly but classic/sniper was the only mode I used. Mod it for a microswitch and you'll get a nice responsive trigger pull.
On an unmilled 03, I like it. I think it would look whole lot better if I had a thin tray for it like the frenzy frame. I think it would really shine on a milled body with a thin tray.
