Titanium Paintball Longbow Barrel System. Who has used one?

[battlegroup]

I'm looking for any experience that anyone might have on the Titanium Paintball Longbow Barrel system. I know all the specs from their website. What I want to know if you have used it, on what marker, what tip length, style of porting, accuracy, and quietness. Also, please rate it on a scale of 1 to 10

Thanks in advance
