I am a golf course superintendent and have many lawns on the side, I am curious on the model to choose in the echo line. Echo is readily available for parts and service here. I am curious on the models like the new SRM 265 and 280, whats the biggest difference in the S, T model variations, i know S is for steel drive and T is torque. Is cable drive better than steel drive? What do you guys recommend? I appreciate the answers!!
