I shoot a new Mathews Z-7. I can get the spitfires to shoot amazing cant get the G-5 strikers to work. I guess the question I have is are they both great broadheads?
G5 all the way.
Use the practice broadheads to get dialed in,then just keep one actual broadhead aside to make sure flying true.A good think about the G5's is it comes with a sharpening stone in a pouch.I shapen my in the tree stand waiting for Whitety to walk by,
gives me something to do.
Good Luck

Your comparing a fixed to a mechanical head--fixed heads wont shoot well unless your bow is tuned, correct spine, and you have correct form. A 125 gr head is a pretty big head--what arrow are you shooting?
