VUR12> Teams may utilize an unlimited amount of the following commercially available pneumatic components: Cylinders, actuators, valves, gauges, storage tanks, regulators, manifolds, and solenoids.
WIthout the mention of pneumaitc tubing this makes us limited to the normal pneumatic tubing rules and makes pneumatic components that use larger diameter tubing illegal. So my question is
-A. Is VexU limited to only 4mm pneumatic tubing?
-B.If the above answer is yes and VexU is limited to 4mm tubing, is VexU also limited to only black Tubing outlined in the linked Q&A www.robotevents.com/VRC/2021-2022/QA/883
Part 2 The tag section only allows up to VUR9 so I can't tag it correctly with the proper VUR12 tag.
