Is the bolt driver worthy of being the only sniper rifle in PS?

but the situation of expanding COF is pleanty to simulate recoil, i don't see any weapon that couldn't be made into PS just fine.

Both the upward moving recoil effect and the expanding cof do the same thing make it harder to hit stuff after a shot, but instead up trying to move your crosshairs back down you have to wait for the COF to close up. It's a very good system for a game like this.
