From your experience how do the Weathermatic Silver Bullets go, or are you all scarred after their problems a few years back? Weathermatic are being pushed by my supplier and are relatively new to Australia. I installed 21 Silver bullets at my last client and I am about to install another 20 at another site. I also installed about 80 T3 rotors as well. They seem to be working fine and I love that they are easy to adjust the arc without the tool like a PGP. I have always used Rainbird DVFs for valves and PGPs for rotors, but my supplier asked me to just give Weathermatic a try. Seeing my supplier has been good to me I agreed to try them. T3's are about 15% cheaper than PGPs and Silver bullets 40% cheaper than DVFs. Seeing things are much more expensive here than over there it is a pretty big difference in price, but I don't want to regret it if they start to fail early on.
