I am excited! I decided to go with the E3D Titan Aero hotend and extruder for my CR-10S. Seemed to have great feedback. Also ordered a couple BLTouches for auto bed leveling for my CR-10S and Tevo Tornado. Printed the mounts from Thingiverse to mount the new hotend/extruder/BLTouch. Will post pics of the process.
