I think the first Game Crusher models were made specifically for Dicks sporting goods by Barnett and sold by them a few years back. I'm guessing that would be the 2.0 model.
I dont know what Pile Driver arrows you have.The ones I had were not rigid at all even though they were heavy with light inserts. They had a very weak spine.Probably the flimsiest crossbow arrows I've ever seen with very little foc and were not accurate for me at all.
