Actually it is more like they knew the issue, they ordered the needed replacement to fix the issue. It takes some time to manufacturer the tubing and until it is delivered why not try something until then as it is merely the test PBR in the first place. We know they did not have the new tubing on hand, nowhere does it state "we replaced tubes with new tubing and have inncolulated", we all knew they were using the same tubing. So once again where is the shock? Where is the hidden agenda?
