The whole point to a certified letter is that you will get confirmation that it was delivered. If you can send an identical letter certified to someone high up at Reynolds, perhaps they'll speak to Paul. Again, it can't hurt.
As for the RZR wheels, a friend who used to rep for Lew in Europe saw the RZR's at Eurobike this year. He handled the wheels, talked with Lew, and talked with other Reynolds folks. The wheels are significantly different. Brake track composition, hubs, spokes, molding, rim composition are all different. And from the pics the bonding of the spokes is different (no more blue epoxy). There's no way Reynolds would just re-issue the Lew wheels: the VT-1's had some significant issues, and Reynolds just doesn't operate that way. When Reynolds bought the first Lew company, back when Lew was selling the Lew Sydney whels (progenitors of the Reynolds Stratus/DV 46 line), they didn't just start selling Reynolds branded Sydneys. No, those wheels were prone to fracturing, so Reynolds reworked the wheels/rims and released, instead, a very successful line of wheels that built the company's reputation.
You can likely get the name of a big muckity-muck at Reynolds either by searching online or by contacting one of the cycling mags or cycling industry mags.
