are these legal for the game this year?

While I haven't checked for differences in this years rules from the last year or two, we last used these in 2012. They (for us) have had a low failure rate, and are great because they are flat and stack well, compared to valves on individual manifolds.

Having said that, they are nowhere to be found, and last year we went to SMC manifold blocks, and SMC SY3240-6LZ double solenoid, and the SMC SY3140-6LZ single solenoid. These worked great, and using the manifold blocks really helped with space issues, as well as being able to quickly add another valve when we needed it.
