I remember baseless bindings, I also remember it was popular to take off your highbacks...All I have to say is there is a reason people don't do that stuff anymore.
It was more of a freestyle thing to ride baseless, if you only ride pipe/park supposedly it gave you a lower center of gravity. I dunno, go for it I guess. If you like it more power to you. I am willing to bet you will go back to based bindings pretty quick.
