Ok looking at Hilleberg Atko and the B.A. Copper Spur 1. To start with I know there is a difference in price. Looks like there is more room in the B.A. And it's a little lighter. I was hoping some of you have been in both and can give a good comparison. Is the B.A. as durable as the Atko, mostly wondering about the floor. Any info on either is appreciated.
