As I am most impressed by having superb trigger action and amazing accuracy I would go for the Original Giss springers every time. You know if you cannot hit your target every time it is not the fault of the pistol/rifle. I have re-sealed quite a few 6's and it becomes old hat and simple.The 10 and 66 rifle are a little more difficult due to trigger parts, but then again it is a job you may have to do only once in the period of ownership.
