Agh yes, the joy of DI2

I have been riding DI2 since it was first introduced. I tried SRAM EAGLE XX1 on my new Jones mtb, but sold that off in a hurry and replaced with XT Di2. It is so nice to have the perfect-ever-time shifting of Di2. Sure, the SRAM stuff worked like it should, but was clunky, noisy, and crude compared to Shimano Di2.
