This is a question for all the bowhunters that shoot indoor, 3D and field as well?

I want new vanes for 3D and field competitions. I'm currently shooting Duravanes 2.5", but wants to change. Anybody that has shot or can give me some advice on the 3D Duravanes (2.3")? Any experiences or other vane recommendations? The vanes will be for 3D and field only....not for my hunting arrows..
