Thanks for sharing it with us. I will admit that I'm a GS fan but nowhere near as big a fan...I still buy what I like and very hardly am loyal to any specific brand. My criteria is reliability, accuracy and a decent maintenance bill when the time comes.
All said, GS continues to enthrall me due to the finishing and robustness. One day soon, I know a spring drive will enter my collection....it is just a matter of time and timing.
