Hey Zendrummers of the world-- Today is my lucky day !! After a long day at the office, I will be visiting Zendrum HQ for my "steroid injection". Yes, that's right, the Z4 upgrade will be installed into my beautiful ZX. I also have the great pleasure of spending some quality time with the Zenmaster, AKA Inspector 109. Learning is vital to progress and I am greatful for this opportunity. I will be happy to share my comments about the upgrade if you are interested. Thanks David, in advance. I am looking forward to it.
