I agree on the float not being one way though. Yes, if it is one way it is because you aren't in the middle.
If 2 degrees each way is adequate there is at least two shimano offerings that have spd on one side and a cage on the other. There are also a couple that have the spd in a cage of sorts. Look at the "All Mountain" models and the "Multi-Purpose" models on the Shimano web site.
My daughter used some Forte campus pedals on the TransAmerica (actually rebranded Wellgo spd compatible). They were OK, but she said on hind sight she would use a two sided spd on tour. She like the reversible option on campus though.
