It's hard to tell a huge difference between starphire and regular with small samples but I've put together 19mm tanks with and without starphire and it's a huge difference when the glass is that thick and you're looking at large sheet of it with light on the other end. I've almost always had starphire tanks and it hardly scratches any easier, if you did something that scratches the starphire it would probably scratch the regular glass as well. Even my wife won't let me build a tank for us without using starphire. Either way is cool though, looks like a sweet setup!
Guess I'll have to start my 405 gallon build
