The impact of tubing sizes

[MotF Bane]

This might be a bit off topic, but does anybody have thoughts on 5/16" ID NALGENE tubing? I haven't found 5/16" ID Masterkleer or Tygon, but I've found Nalgene tubing in town. By the way, the stuff I found is 5/16" ID 1/8" Wall 9/16" OD. Almost as large as the Masterkleer. Of course, just holding it here, no Smartcoils and no liquid inside, it's definitely making the one-inch bend radius using my hands.
