It's an Asymmetrical-Symmetrical highback easy to roll in hard to roll out.
Forgot about the asym straps.
youtube search has a good overview of both. Internet, all-around, nice guy spenser says the force is the most responsive binding in the lineup, that's under $250
Due to the baseplate the SL is probably between the atlas and the force as far as response goes.
what does Asymmetrical-Symmetrical mean? Isn't that contradicting?
