A threw the Vamp a few more times the last couple days and it has broken into an understable flight. Now it is flying more like a fresh DX Leopard (but faster). If it stays this way, it will fill the understable fairway slot perfectly. It will hyzer-flip with 280-300 feet of power. Thrown flat with the same amount of power, it has a glidey s-curve with a gentle fade. At 330 feet, it turns the entire flight and does not fade back. I will definitely put this in my bag if it makes it to production.
This sounds wonderful! If Vibram puts this on the market, it'll just have to take my money!
