Loosest board???

I ride at average ability. I am looking for the loosest board available (not the Roam). Due to my age and injuries I will not be doing any inverts but would like to become an accomplished surface rider. Presently, I ride an '03 Belmont with the center fins removed. I also own a 133 Fish which I ride with factory fins. I also have a Temet which I ride totally finless. I just purchased an '06 Absolute Platinum which I ride finless. I am disappointed that the Absolute still is not loose enough. The reviews I've read indicate that the Transcend is very loose in the neutral position, but grips really well when on edge. Can anyone help me choose a board that is VERY loose while riding neutral, but has good hold when on edge for charging the wake. Someone suggested the O'Brien Natural. I have a Roam on order but I want an everyday board that is very loose but locks down well on edge. How about the Valhalla?
Thanks in advance. Please respond on this site. I am using someone's computer.
