This response is not quite correct. <R100> allows 2005's tubing (i.e. SMC TIUB07, not Freelin-Wade), cylinders and solenoid valves, subject to the usual limits. Furthermore, <R26> extends this to any "previous year's cylinder, valve, or tubing", despite the apparent discrepancy with <R100>. However, 3/8" tubing, since it has never been in the kit, is clearly illegal.
Previous years' tubing, even of the same size as this year's tubing isn't "identical" to the 2006 tubing. (We don't apply "same ratings" ≈ "identical" to other pneumatic components, so I think that there's a precedent that supports my criticism.)
