I messaged him on Facebook a few days ago, and he said there was no plan for any upgrades . Do you and he discuss in details about when he may release the upgraded version?Gene and I touched on the subject of updating the M61HOT and M91T. He would be happy to do a run for us if we provided the emitters, but he said that everything is getting the updates we have already seen roll into the E2XT and Hound Dog XT heads. For this reason, I am not keen on running a GB on it, but it's taken a bit longer than I though it would too though I bet we aren't long for a new batch of updated product!
