Sorry to hijack your thread, but did they have any of the new D2/WiFire models in the Roadshow? Trying to figure out if it might be worth a roadtrip anywhere for a new Pro 575 or not since they don't appear to be hitting my local warehouse this spring pass through. Related to your thread, I had noticed that the new probes where considerably shorter but hadn't really thought about it...what's different is rather than up along the side of the barrel, they now have them pointed into the chamber...but they are really short now that you've pointed it out.
