Look down at your sig - "Takahashi FC...." Now look back up, and take a deep breath!
If you've sourced the scope I think you have, then there is no where for you to go after that in terms of an upgrade. You will have attained strehl perfection, the scope of a lifetime, and (i can't believe im typing this...) the scope in that ad would be a disappointing backwards step.
stay strong brother!
